In research, the center focuses on issues related to global innovation practices and theory. The center's educational program includes a range of courses leading to a "global concentration" in several Howe School graduate programs. The center also plans a series of executive courses, as well as student exchange programs, at the undergraduate and graduate level with global corporations and international business schools.
The Center for Innovation in Engineering and Science Education (CIESE), www.ciese.org, part of the Charles V. Schaefer, Jr. School of Engineering and Science, was founded in 1988 to lend Stevens' expertise in integrating computers into its curriculum to improve K-12 science, mathematics, engineering, and technology education. CIESE's mission is to increase the pool and improve the capabilities of all students to pursue higher education and careers in technological fields and to support the Stevens education by catalyzing and fostering innovation in the teaching and learning of engineering, science, and mathematics. CIESE’s outreach efforts impact pre-college and university educators and students in order to improve the quality of students and advance the practices of engineering, applied science, and technology management.
In pursuing its mission, CIESE's work has encompassed both pre-college and post-secondary educators. The Center assists K-12 educators in exploiting the power of technology to improve teaching and learning in engineering, science, mathematics, and other disciplines. These activities complement Stevens objectives by helping students acquire the foundations necessary to excel in science, mathematics, and other subjects. Achievement in these "gateway" subjects enables students to go on to the advanced study required in engineering and other technologically-rich fields.
CIESE works collaboratively with teachers, school system administrators, and university faculty to provide intensive, hands-on training, support, and counsel to infuse technology in meaningful ways into the curriculum. Technology is seen as both a tool for teachers and a new mode for bringing exciting content to students. In the past, students might have read in a textbook about earthquakes that happened several years ago; today it is possible for them to log onto a Web site and see the location and intensity of earthquakes that have occurred within the past 24 hours. Bringing these real-world phenomena into the classroom both motivates and engages students to learn in ways not possible with more traditional tools. Through partnerships with school districts, as well as colleges, universities, and other organizations in New Jersey and four other states, CIESE has trained more than 20,000 teachers and impacted more than a half-million students. CIESE’s Internet-based curriculum materials have been recognized by organizations such as the White House Office of Science & Technology Policy, the U.S. Department of Education, the American Association for the Advancement of Science, the National Council of Teachers of Mathematics, and other organizations. More than 100,000 students participate in CIESE’s real-time data and global telecollaborative projects each year. CIESE is currently implementing a $1.5 million U.S. Department of Education grant to transform teaching and learning in science and mathematics education for pre-service teachers through partnerships with 33 community colleges. CIESE has also implemented large-scale technology training programs, including a five-year, $9.28 million U.S. Department of Education Technology Innovation Challenge Grant; a three-year, $750,000 AT&T Foundation grant; a three-year, $600,000 New Jersey Department of Education grant; and a three-year, $1 million program to strengthen science education for New Jersey's neediest schools; as well as several specific teacher-training programs with New Jersey and New York schools and districts.
Central to CIESE activities are unique and compelling Internet-based curriculum materials for K-12 science and mathematics education. The Savvy Cyber Teacher® (SCT) workshop series is a 10-part, 30-hour teacher-training program providing educators with hands-on experience using Web-based applications in order to engage students in authentic science investigations and problem-solving activities using real-time data and global telecollaboration. SCT materials and other training programs are available to schools and teachers through grant-funded programs or fee-for-services arrangements with CIESE.

The Center is composed of three integrated facilities supported by the Instrumentation and Design Group that designs and manufactures the specialized equipment needed to support research activities and by the Computation Support Group that ensures the availability of high end computer and visualization power:
The Davidson Laboratory
The Davidson Laboratory, founded in 1935, is one of the largest and most renowned hydrodynamic and ocean engineering research facilities in the nation. Pioneering marine hydrodynamic studies in both physical modeling and computer simulation of marine craft designs (ranging from high-speed planning boats to submarines) have contributed to the Laboratory’s international reputation. The primary research facilities are two unique wave tanks. The first is a high-speed towing tank with a length of 320 feet, width of 16 feet, and a variable water depth of up to 8 feet a result of a recently completed a major renovation. A monorail-supported cable-driven carriage is capable of speeds up to 100 ft/sec. The tank also contains a programmable wave maker capable of generating monochromatic and random wave fields, as well as several types of wave spectra. Shallow water conditions can be simulated in the tank with the installation of an adjustable slope false bottom. Nearshore beach conditions are studied by placing 40 tons of quartz sand on a 65-foot-long, 1-on-20 sloping false bottom. The tank’s improved instrumentation, glass walls for viewing and photography, and public access improvements further enhance the Laboratory’s contributions to fundamental and applied research in ship design, hydrodynamics and ocean engineering. The second tank is a rotating arm and oblique-sea basin, with dimensions of 75-feet-long by 75-feet-wide and a variable water depth of up to five feet. The facility has been designated an International Historic Mechanical Engineering Landmark, one of only two of its kind in the nation and was featured in the February 1996 issue of Sea Technology.
The Marine Observation and Prediction Laboratory
The Marine Observation and Prediction Laboratory addresses the many challenges facing estuarine and coastal communities – including natural and man-made hazards by improving our ability to detect, understand, predict, and respond to changes to the marine environment. Estuarine and coastal field research is accomplished through the use of the Laboratory’s two research vessels. The newest is a 45-foot research vessel fully equipped for environmental studies in the Hudson estuary and adjacent coastal ocean. The vessel is powered by a 400hp Cummins 6 cylinder diesel engine with a 400 gallon fuel capacity. It cruises at 12 kt with a top speed of about 14 kt. Onboard capabilities include a full electronics suite including gps, radar, and chartplotter, a 50 gallon freshwater tank, berths for 3, and a 1500-pound capacity A-frame winch. Research instrumentation includes topographic and bathymetric surveying equipment, a CODAR high frequency radar system, Acoustic Doppler Current Meters, PUV meters, laser-based Suspended Sediment Particle-size Distribution Meters, and a Turner-design fluorometry system. The State of New Jersey funds the Laboratory to administer the New Jersey State Coastal Protection Technical Assistance Service (CPTAS), a unique resource created to both inform and counsel New Jersey citizens and government officials regarding coastal protection technology.
Modeling systems for estuarine and coastal ocean nowcasts and forecasts are being constantly refined to provide the most accurate realizations possible of the marine environment. The basis of the modeling systems is the Princeton Ocean Model (POM) and its shallow water derivative model, ECOMSED (Estuarine and Coastal Ocean Model with Sediment Transport). They are the central modeling component of the Laboratory’s New York Harbor Observing and Prediction System. NYHOPS is a real-time observation and forecasting system that provides continuous information regarding present ocean and weather conditions throughout the region and forecasts of conditions out to 48 hours. The real-time data and model forecasts are disseminated to the public via the Internet at www.stevens.edu/maritimeforecast.
Maritime Security Laboratory
Maritime Security Laboratory facilitates advances in methods and technologies relevant to maritime security. The Laboratory is designed to enable system-level experiments and data-driven modeling in the complex environment of an urban tidal estuary. The focus of the laboratory is on underwater threats and threats from small craft with hostile intent. The laboratory is constantly working to address future threats as they become identified. It has created and demonstrated a set of innovative sensing technologies and methodologies, and a set of complementary data integration and data distillation methodologies, which, when used together, show a high potential to reliably protect ships. Additional types of research prototype sensors, sensing systems, sensing methodologies, and refined detection enhancement methodologies are currently being modeled and experimentally tested. A laboratory infrastructure has been established in the Hudson River, connected to the Stevens campus in Hoboken. This laboratory infrastructure is being augmented with additional platforms in the water, including unmanned, underwater vehicle’s (UUV’s), and additional on-shore data integration and data distillation capabilities to support a wider range of sensing technologies, sensing systems, and detection-enhancement methodologies.
The Laboratory provides researchers, and others who may wish to use the laboratory, with a real-world testing environment and an infrastructure of in-the-water platforms, communication links, and information integration and distillation systems (computers, associated software-based processing algorithms, and stored data): that are being leveraged to quickly and easily try out new types of sensing technologies, sensing systems, and sensing /detection methodologies; including methodologies that combine multiple types of sensors and sensing systems.
Mass spectrometry, a rapidly advancing scientific discipline with tremendous employment potential, has far-reaching qualitative and quantitative applications in environmental, biological, biochemical, pharmacological, forensic, and geochemical fields.

Our instruments are amenable to a wide variety of organic compounds, including proteins, peptides, amino acids, alkaloids, steroids, flavanoides, saccharides, lipids, nucleic acids, polymers, petroleum products, and organo-metallics. Our mass analyzers are based on time-of-flight and quadrupolar techniques. One of the new instruments featured in this center is a Q-TOF API-US mass spectrometer. This hybrid instrument incorporates two mass analyzers in tandem: a high performance quadrupole filter as the first stage and a orthogonal-acceleration time-of-flight analyzer with a mass resolving power of 17,500 as the second.
Another research facility is the Center for Product Life-Cycle Management (CPLM), a focal point for both information and technology on plastic products over their life-cycle: design, manufacture, use, and disposal. Working with industry and government, CPLM emphasizes the development of products and fabrication processes that reduce the potential for significant environmental problems and risk, and promote sustainable growth. CPLM’s activities include contract product and process research, engineering studies, educational and training programs, and technology transfer industrial extension services. The center uses three other facilities:
- The Blandford Water Quality Laboratory is equipped for all standard chemical and microbiological determinations used in the water and wastewater field. These include atomic absorption spectroscopy, gas chromatography, and high-performance liquid chromatography.
- The Waterfront Tower Facility, a ten-story, 3,000-square-foot tower, is used to conduct pilot-scale waste treatment and destruction technology development and testing. This unique facility can accommodate construction of very high treatment setups. Several pilot-scale setups are in operation, including a 40-foot-high steam-stripping parked column.
- The Research Vessel, Phoenix, is used for conducting pollution studies in estuarine and coastal waters. This 25-foot-long vessel has been equipped to perform dye tracer experiments, collect water quality samples, and obtain observations of water velocity, salinity, and temperature. The Phoenix is named after an early 19th-century steamboat constructed by the Stevens family.

The Highly Filled Materials Institute (HFMI) (http://www.hfmi.stevens.edu/) was established at Stevens Institute of Technology in 1989 to investigate, both experimentally and theoretically, the rheological behavior, microstructure, processability, and ultimate properties of highly filled materials, including concentrated suspensions and dispersions of generally polymeric liquids incorporated with rigid particles at concentrations which aim to approach the maximum packing fraction of the solid phase.
Highly filled materials are encountered in various industries related to life sciences, personal care products, intermediary and final food products, batteries, polymeric master-batches and compounds, construction products, energetics, composites, magnetics, and ceramics.
The focus of the Center has broadened considerably over the years and encompasses the synthesis, compounding, characterization, simulation, and processing of myriad complex fluids including biodegradable polymers, nanosuspensions, gels/hydrogels, vesicular surfactants and other structured fluids.
One of the current major focus areas of HFMI is in the development of biomaterials, especially biodegradable scaffolds for tissue engineering applications, and constructs for controlled drug release. For example, HFMI has developed a number of novel methods to precisely fabricate three-dimensional functionally graded scaffolds which allow changes in composition, porosity, mechanical properties and biodegradation rates to vary as a function of location in the scaffold. HFMI has also developed a hybrid process which has merged twin screw extrusion with electrospinning to allow the generation of nanofibers with tailored nanoparticle concentration profiles. The long-term areas of research include the understanding of the wall slip behavior, development of flow instabilities, inverse problem solutions for parameter determination, mathematical modeling using analytical and numerical methods and processing of complex fluids, especially viscoplastic fluids subject to wall slip.
HFMI has carried out over 120 grants and contracts for companies and Government organizations. This high level of funding activity keeps HFMI in close contact with multiple industries concomitantly and allows HFMI to better define its research goals. An industrial advisory board guides HFMI in carrying out short- and long-term contract research for government agencies and corporations. Sponsored research is carried out by the professional staff of HFMI along with research assistants.

The Laboratory's mission is to pioneer new technologies for high-assurance and secure systems and prototype tools that can provide guarantees that a system will not exhibit unpredictable behavior in a hostile environment. The objective is to consolidate and organize research and tool-building efforts already underway at Stevens. The Lab is funded by grants from the New Jersey Commission on Science and Technology, the National Science Foundation, and the Stevens Institute of Technology Technogenesis Fund. The facilities of the Lab include several desktop machines, PDAs with wireless Ethernet, and Bluetooth devices for experimentation. The Lab is affiliated with the New Jersey Institute for Trustworthy Enterprise Software.
Part of the research work is focused on building better trust models for components. Some of this work is using static analysis techniques to check access control and information flow properties for untrusted components. There is also work on pushing type safety from high-level languages down to the assembly language level and, in the process, checking properties of heap space usage. Other work has been on type systems for dynamic linking and "hot" updates of program libraries at run-time.
Another thrust of the work in the Lab has been in network security, particularly for wireless networks. Work continues on attacks that can be mounted on ad hoc wireless networks and in the design of new authentication and key establishment protocols that can be used to improve the security of wireless communication in general. Recent work has also looked at type-based approaches to cryptography to specify and ensure trustworthiness guarantees for communication channels.
A new area of research at the Lab is the study of secure electronic transactions, such as banking operations or voting. The work consists of using secure patterns of communication described using type-systems to detect unauthorized modification of data between trusted communicating parties.
The Lab has a seminar series where guests from industry and academia, as well as members of the Stevens community, present recent advances in all areas of computer security.
Today, educating engineers, scientists, and managers requires more than traditional laboratory facilities. The Lawrence Schacht Management Laboratory provides facilities to learn and practice business skills in realistic environments: to learn the art and science of making effective presentations, to understand and improve interpersonal and organizational skills, to develop the computational skills needed in today’s competitive world, and to conduct research in management and technology management.
The laboratory is composed of a seminar room and five conference rooms, a computation laboratory, and a networking and video control center. Video cameras and screens in each of the conference rooms can be operated and controlled remotely from the control center. Network and video connections are installed throughout the laboratory, enabling laboratory activities to combine the use of audio, video, and computing techniques.
These facilities are well-suited for use in many academic programs. For example, students practice presentation skills in the seminar room, and undergraduate and graduate students simulate a variety of managerial situations in the conference rooms as they learn the dynamics of small groups.

- Center for Controlled Quantum Systems
The Center for Controlled Quantum Systems (CCQS) is a cross-disciplinary research center involving collaborations between multiple research groups focusing on one of the last challenges in research: controlling (and thereby employing for future application) the quantum system. New waves of technologies are normally connected to breakthroughs in research which allowed for greater control of nature and opened up ways to harness the newfound potential. Today's limit of control is mostly based on the quantum mechanical nature, and while physicists have explored quantum mechanical phenomena of quantum systems like atoms, molecules, and the solid state for decades, only a few have tried to control the dynamics of these systems in real time.
One of the main directions of the center is based on optical techniques to control quantum systems. The advent of ultrafast lasers and laser cooling techniques in recent years has finally opened up the possibility of controlling quantum dynamics. This can be achieved using ultrafast femtosecond lasers to either probe the systems on time scales much shorter than the time scale for which quantum mechanical phase coherence is maintained, or by directly manipulating the environmental sources that destroy phase coherence. By contrast, laser cooling and trapping techniques can be used to create systems with temperatures so low and well isolated from their surrounding environment that phase coherence times can be increased by many orders of magnitude. The ability to precisely control the phase and amplitude of laser pulses provides a high degree of customization in their interaction with matter.
The work in this center will contribute to and direct the development of new quantum mechanics-based technologies, such as quantum computers, new types of solid state and interferometric sensors, and light sources with customizable photon statistics and coherence properties. A unique characteristic of this center is the close collaboration between theoretical and experimental groups. This provides the opportunity for students to gain both theoretical and experimental research experience working on the same project.

- Ultrafast Laser Spectroscopy and Communication Laboratory - Prof. R. Martini (WWW.FEMTOLAB.US)
The realization of ultrahigh-speed communication networks at and above Terahertz (THz) bandwidth is one of today's most challenging problems, as the limiting factors are given by fundamental physical properties and laws. To overcome the restrictions, new concepts and materials have to be invented and utilized. In this laboratory, we investigate the high-speed response of new lasers and materials, as well as passive and active optical systems using ultrashort laser pulses (<100fs) to develop towards higher speed networks. In addition to this, the ultrashort laser techniques in this laboratory enable us to apply many different measurement techniques, accessing the world of the "ultrafast." Time-resolved Terahertz (THz) spectroscopy setup, for example, gives us the unique ability to measure optical, as well as electrical, properties in this ultrahigh-speed frequency region and use it for new and fascinating applications in this new "frequency world."
