Degrees Offered

M.S., Ph.D.

Program Description

The Department of Chemistry and Biochemistry at UMBC offers graduate programs in the disciplines of analytical, biochemical, organic, inorganic and physical chemistry leading to the doctoral degree in Chemistry (including Biochemistry). The diversity of faculty research represented in the program enables students to combine the study of energetics, structure and dynamics of chemical systems with their application to problems in the biological sciences. A masterís in these same chemical disciplines is also available through the Department of Chemistry and Biochemistry at UMBC. (See also joint programs in Biochemistry, Molecular and Cell Biology and Marine-Estuarine Environmental Science.)

Degree Requirements

All students enrolled in the M.S. and Ph.D. programs are required to complete a core program of study consisting of four out of a selection of 400- and 600-level courses in all areas. This core can be completed during the first year of graduate school.

Doctoral candidates are expected to enroll in other advanced courses in their area of specialization in addition to the core program of courses. Completion of a minimum of three additional courses (nine credit hours) at the 600-level or higher, along with 12 credit hours of CHEM 899: Dissertation Research, is required. A minimum of two semesters of teaching is required of all doctoral candidates.

A candidate for the masterís degree must complete 30 credit hours of course work (including the core program), of which 18 credits must be at the 600-level or higher. The program is flexible enough to meet a wide range of student interests. Students electing to do a masterís thesis will complete six credit hours of CHEM 799: Masterís Thesis Research. A non-thesis option, in which additional course work is undertaken in lieu of the thesis, also may be selected. In this case, the student will obtain some experience in research by completing CHEM 600: Advanced Laboratory Projects.

In either program, the remaining courses and seminars may be taken in areas of interest to the student(with approval of their advisor), including the biological sciences, physics, mathematics, chemistry and chemical engineering. Prior to registration for the first semester of graduate study, each new graduate student will meet with a member of the graduate committee who will assist in planning and implementing the degree program until a research advisor is selected.

Each doctoral student will begin a laboratory rotation in the fall semester and select a research advisor prior to the start of the second semester of study. When a student elects to do dissertation research with a particular faculty member, that faculty member becomes the studentís research advisor. During the first year of graduate study, masterís students who select the thesis option will consult individually with the members of the faculty to discuss the choice of a thesis topic. If a thesis advisor is chosen, the advisor will become the studentís counseling major advisor. All entering M.S. and Ph.D. students are asked to take placement examinations. Students whose background is deficient in specific areas will be required to enroll in appropriate undergraduate courses and obtain a grade of ďBĒ or better. Students excelling on those examinations may be exempted from specific core courses.

For all masterís students, a final oral examination will be arranged in accordance with the procedures of the department. This examination will follow completion of formal course work and the submission of either the masterís thesis or, in the case of the non-thesis option, a scholarly paper indicating the studentís familiarity with an area of modern chemical research. In addition to course requirements, doctoral students must successfully complete the four levels of progression toward the Ph.D. degree:

  1. Literature Review
  2. Advancement-to-Candidacy Examination
  3. Original Research Proposal
  4. Final Dissertation Defense

In each of these steps, the student is evaluated by a committee consisting of at least four program faculty,(three of whom are from the studentís sub-discipline, one of whom is outside this sub-discipline)and one member from outside the program. The members of this committee are chosen by the studentís research advisor in consultation with the student. To help monitor the studentís progress toward the Ph.D. degree, the committee should vary as little as possible. There is no language requirement for the M.S. or Ph.D. degrees. The Department of Chemistry and Biochemistry has a brochure that describes its graduate programs and the research interests of its faculty. For a copy of the brochure, or for specific information on the M.S. and Ph.D. programs in chemistry, contact the department office, 866-743-8622. A frequently updated version of the brochure may be accessed via the UMBC homepage at www.umbc.edu/chem-biochem. The Graduate Student Handbook is also available from the department office.

Program Admission Requirements

Most students entering the M.S. or Ph.D. programs will be expected to have majored in chemistry, or biochemistry, but applications are welcome from students who majored in other fields, provided their records indicate the ability to complete the program successfully. The desired undergraduate background includes courses in organic, analytical and physical chemistry; physics; calculus; and some work in the biochemical sciences. Scores on the Graduate Record Examinations (GRE) (verbal, quantitative and analytical tests) are required. The GRE Advanced Chemistry Test is strongly recommended.

Facilities and Special Resources

UMBC students are offered hands-on access to an extensive array of tools for modern chemical and biochemical research. The departmentís specialized research instrumentation includes calorimetry, chromatography, stopped-flow and temperature-jump kinetics, transient laser spectroscopy (including nano-second laser flash photolysis, pico-second and femto-second pump-probe and picosecond fluorescence systems), nuclear magnetic resonance spectroscopy (including one 200-, one 300-, one cryoprobe-equipped 500-, two 600- and one 800-MHz instruments), X-band CW electron paramagnetic resonance spectrometry, circular dichroism, X-ray diffraction, infrared spectroscopy, atomic absorption and gas chromatography mass spectrometry and both a 7 and 12 Tesla Fourier transform ion cyclotron resonance mass spectrometer apparatus, as well as extensive molecular modeling and computational chemistry facilities.

The department also hosts a BiochemistryMolecular Characterization and Analysis Complex (MCAC), which specializes in the analysis of environmental and biological molecules (e.g., biopolymers, peptides and glycoproteins). In addition to TOF/FT, a laser desorbtion mass spectrometer and both 500- and 600-MHz NMRs, this center houses one of the few tandem mass spectrometers located in academic institutions worldwide. The Howard Hughes Medical Institute suite houses a second 600- and an 800-MHz NMR instrument, both of which are used for high-dimensional studies of HIV proteins, metallo-biomolecules and macro-molecular interactions. The Albin O. Kuhn Library and Gallery contains more than 2,500 volumes of chemistry and biochemistry texts and subscribes to more than 150 chemistry and biochemistry periodicals.

Outplacement Success

Students completing the M.S. or Ph.D. degree programs at UMBC have continued their graduate or post-doctoral training at such competitive and prestigious institutions as the Johns Hopkins Medical and Graduate Schools and MIT, Harvard, Cornell, Columbia, Brandeis and Georgetown universities and have gone on to be faculty at prestigious universities across the country. Program graduates have also gone on to be leaders in the government and industrial workforce, finding employment with local, national and international organizations such as the U.S. D.o.D., NIH, the FDA, Ciba-Geigy, DuPont-Merck, Eastman Kodak-France, Glaxo Smith Kline, Proctor & Gamble, the U.S. Patent Office, etc.

Financial Assistance

Support is available on a competitive basis to students accepted into the program. Qualified first-year students are usually offered teaching assistantships. Research assistantships are often available for students actively engaged in thesis research. In addition, students are encouraged to apply for nationally awarded graduate fellowships. Student loans are available through the Office of Financial Aid.

Fellowship Opportunities at the Interface of Chemistry and Biology

UMBC recently has authorized a limited number of fellowships for incoming graduate students who are interested in both the areas of chemistry and biology. These fellowships aim to prepare students for the challenges of the 21st century, which will reward those who have expertise in more than one area of science. Even now, those scientists who can bridge the gap between biology and chemistry are in high demand in such areas as the pharmaceutical industry. Synthetic chemists who are knowledgeable about metabolism and biologists who understand the physical principles governing the interactions between macro-molecules are widely sought after.

Fellowship recipients will obtain their Ph.D. degree in an area of the chemical or the biological sciences, but with an additional focus in the other discipline. Each course of study will be individually tailored to take into account studentís strengths and interests, but all will include coursework at an advanced level in the biological sciences and chemistry, as well as biochemistry. In addition, students will carry out research rotations in the laboratories of faculty members from both disciplines and will attend seminars from both departments.
