Department of Chemical Engineering
In the academic year 2000-2001, the department maintained its high productivity and visibility. We continued as number one amongst chemical engineering departments in the annual academic survey of the US New and World Report. We graduated 21 doctoral candidates together with 40 M.S. students, totaling 61 advanced degrees. The research dollar-volume of over $19 million was reached to support departmental research activities.
The department's undergraduate enrollment stands at 232 students with approximately 85 students per graduating class and the percentage of women now reaching 56 percent. A $3.4 million renovation to the entire sub-basement of Building 66 is underway in order to create a state-of-the-art undergraduate teaching laboratory ready for student use in the spring term of 2002.
The graduate student enrollment is stable at 206 students with 166 in the doctoral program and 40 master's students, most of whom are in the David H. Koch School of Chemical Engineering Practice. The class includes 73 foreign, 59 female and 32 minority students, of which 18 are Asian American. This year, we received 372 applications for our graduate program and offered admission to 89 students, with 49 accepting our offer.
Professor Alice P. Gast from Stanford University will join MIT in the fall of 2001 as Vice President for Research and Associate Provost for the Institute and as the Chemical Engineering Department's first holder of the Robert T.

The Molecular Engineering of Biological and Chemical Systems (MEBCS) was initiated in 2001 as one of the five graduate programs under the Singapore-MIT Alliance, a joint educational and research enterprise between MIT, the National University of Singapore (NUS), and the Nanyang Technological University (NTU). Chaired by Professor Jackie Ying (MIT) and Professor Miranda Yap (NUS), the MEBCS program offers two innovative courses of study that integrate a molecular-level understanding of biological and chemical phenomena with advances in process engineering for the life sciences and fine chemical industries. The professional master's (S.M.) degree program prepares graduates for the shaping and solving of complex problems through rigorous coursework, which presents advanced engineering concepts tying together multiple-length scales-molecular, microscopic and macroscopic-through a close coupling to biological, chemical and materials sciences. The S.M. degree offers students an opportunity to interact with the MIT faculty during the Immersion Program on the MIT campus. Additionally, S.M. students participate in two intensive six-week Industrial Immersion projects at international pharmaceuticals and fine chemicals companies. The Ph.D. degree program prepares graduates for advanced careers in industrial research and development centers, research institutes, and academia, with emphasis on synthesis skills, engineering design and interdisciplinary approaches. It includes advanced coursework and independent research with a full semester of study and research at MIT. Students conduct novel research under the joint supervision of MIT and Singapore faculty on structured fluids, surface functionalization, microstructure tailoring, and materials design in relation to fine chemicals and pharmaceuticals synthesis as well as on molecular and cellular aspects of biotechnology, genomics, bioinformatics, proteomics, drug design, and delivery that underlie advanced bioengineering.
Table 1. Undergraduate Enrollment over the Last Eight Years
The undergraduate program remains strong with excellent students. We have completed a review of the undergraduate curriculum, which has resulted in the proposal of several significant changes. We will be introducing a new subject, 10.10 Introduction to Chemical Engineering, which will be the first proposed required subject for the major, as well as serving as a subject to introduce freshmen to Chemical Engineering. In addition, the Integrated Chemical Engineering (ICE) sequence in the senior year will be restructured to allow more time to consider the design process. Employment opportunities for our graduates remain strong across a wide variety of industries, including biotechnology, semiconductor fabrication and consulting, as well as the traditional chemical and petroleum industries.

Engineering Bioseparations in Microfluidics Devices (Professor Patrick S. Doyle)
Biological assays routinely call for the separation of proteins, DNA, and cells. The demand to perform these assays faster and with smaller sample volumes is rapidly spawning new developments in microfluidic and lab-on-a-chip devices. Professor Doyle's group has been working with Dr. Viovy at the Institut Curie to develop novel ways to rapidly separate large DNA using custom 'obstacle courses' as a sieving medium in lab-on-chip devices. The obstacle course is constructed from superparamagnetic colloids which self-assemble into a regular, rigid matrix when a magnetic field is applied. The matrix resembles a 2-dimensional array of posts through which the DNA are driven with an electric field. In contrast to standard polymer gel matrices, the colloidal arrays can have extremely large and homogenous pores (~1-20 μm), which is advantageous for separating large DNA. Experiments have shown that separations are an order of magnitude faster than standard techniques with these new matrices. The Doyle group has also been studying DNA separations at the single molecule level using fluorescence video-microscopy. By watching and analyzing how the molecules collide and slip past obstacles they hope to develop mechanistic theories, which can then be used to rationally design improved obstacle courses. The Doyle group has also begun to study the self-assembly of the superparamagnetic colloids themselves. The colloids are confined in channels that are of comparable size to the bead diameter. In such confined geometries the self-assembly process is extremely sensitive to channel geometry, surface topology and magnetic field history. The aim of this work is to be able to guide the self-assembly process to create tunable matrices for microfluidics applications.
Modeling, Simulation and Optimization of Process Dynamics (Professor Paul I. Barton)
Chemical and biological manufacturing processes are large and complex systems, regardless of the actual physical scale (e.g., oil refineries, micro power generation systems, biological cells). Understanding and manipulation of time dependent (or dynamic) phenomena are crucial to the engineering of such systems, and has impacts on process efficiency, process economics, process safety and environmental performance. The unifying theme of research in Professor Barton's laboratory is the study of such large-scale dynamic systems.
The chemical processing industries make extensive use of general-purpose mathematical modeling software that supports the formulation, debugging and numerical solution of large-scale dynamic models. The software systems ABACUSS II (Advanced Modeling Environment and Embedded Simulator) and DAEPACK (Differential-Algebraic Equation Package), under development in Professor Barton's laboratory, represent the state-of-the-art in this technology, implementing advances in the areas of problem representation, software design, and numerical algorithms.
Important problems in process operations include the design and optimization of major process transients such as start-up, shut-down, and changeovers, the design and verification of automatic safety systems for abnormal situation management, the interaction between these issues and plant/equipment design, and the design of inherently dynamic systems such as batch processes and periodic processes. In recent years, there has been a growing awareness that process behavior during such operational transients experiences significant discrete aspects superimposed on the underlying continuous dynamics governed by conservation principles. These discontinuities (triggered by events) may be caused by control actions and/or disturbances (e.g., starting/stopping pumps, the action of an interlock system, equipment failures, etc.), or caused by changes in the physical regime (e.g., thermodynamic phase changes, changes in the flow regime, irregularities in the geometry of vessels, etc.). A natural detailed modeling framework for such situations is that of hybrid (discrete/continuous) dynamic systems. Research in Professor Barton's laboratory has pioneered the development of theory and numerical methods for hybrid dynamic systems. These include contributions to the modeling, simulation, sensitivity analysis, and optimization of hybrid dynamic systems. For example, these advances demonstrate that a start-up procedure may be designed automatically by formulating the problem as a hybrid dynamic optimization.
The batch mode of process operation is experiencing a renaissance due to the increasing importance of the pharmaceutical, biochemical, and advanced materials industries. Batch processes are ideal for the flexible manufacturing of multiple products with small production volumes, and are, thus, favored by these high-technology industries. Batch processes are inherently dynamic systems that do not have a steady-state; instead, they are forced
by sequences of discrete control actions through their operational cycle. Professor Barton's laboratory has pioneered the development of detailed dynamic model-based techniques for the conceptual and detailed design of batch processes. Another thrust of research has focused on environmental issues in the design of pharmaceutical processes, using thermodynamic insights to develop processes that have highly integrated solvent recovery and recycling. This thrust has also motivated a number of contributions in the study of batch distillation of azeotropic mixtures (an azeotropic mixture does not change composition on boiling, which is a problem for separation via distillation because the intention is to exploit composition changes on boiling). For instance, we have invented novel batch distillation processes for azeotropic mixtures that can be applied on a small scale in a flexible manufacturing environment.
Increasingly, engineering problems in design and operations are being posed as formal optimization (or mathematical programming) problems. This has the advantage that, if a suitable algorithm is available, then an optimal design or operating policy may be found automatically, and often very non-intuitive solutions are discovered that improve the performance of the system significantly. Integer (binary) variables are often introduced to represent the choice of whether or not an element is to be included in the final design, or to represent the sequencing of events in an operational problem. The global solution of mixed-integer nonlinear optimization problems where the participating functions are nonconvex has been an unresolved problem in the literature until very recently, and work in Professor Barton's group has been amongst the first to develop suitable algorithms. Current work is now extending these advances to dynamic optimization problems that involve integer decisions.
