Hot Major

Forensic Science: Forensic scientists are crime solvers. They collect and analyze physical evidence found at the scene, analyzing fingerprints, body fluids, firearms and drugs. Communicating their findings with thorough scientific reports, they also preserve evidence, testify in court, and discuss evidence collection with law enforcement personnel, all while playing a vital role in the criminal justice process. Check out the career opportunities and curriculum of the Department of Chemistry And Biochemistry’s degree in Chemistry with a concentration in forensic chemistry.

Interested in Biochemical, Biomedical, or Medical Careers?

Interested in Biochemical, Biomedical, or Medical Careers?

Biochemistry combines the study of living systems with chemistry. What is the chemical basis of heredity? What fundamental changes occur in disease? How do living things obtain and use energy? If you are interested in a career as a medical doctor, immunologist, toxicologist or biomedical researcher-- then a biochemistry degree is an excellent choice as a major.

Did you know? — Beginning in 2015, the Medical College Admissions Test (called MCAT) will emphasize more biochemistry.

The Department of Chemistry and Biochemistry hosted professors from two Nigerian universities on November 20th, 2015. The visiting professors toured several selected Water Quality Research and Management Laboratories including the Water Quality Research Laboratory located in the Department of Chemistry & Biochemistry. Plans are to participate in the preparation of a research paper aimed at spearheading future collaborations in Global Water Resource programs and to collaborate with HU professors on water quality research.

The Water Quality Research Laboratory was established to identify and study contaminants that impact natural water systems in the Hampton Roads area. While supporting research in water quality, the lab also provides training and service learning opportunities for students, and serves as a resource for the immediate Hampton Roads community. Dr. Isai T. Urasa, Chair and Professor of Chemistry, is the Director of Water Quality Research Laboratory.

Annual Chemistry Dinner – December 4, 2015

The Department of Chemistry and Biochemistry held its annual dinner bringing together faculty, staff, chemistry majors and alumni guests—Dr. Kaiulani Houston (HU Chem Class of '08) and Ms. Reena Blade (HU Chem Class of 2014 and currently @Purdue). Janay Little, a traditional chemistry junior, greeted everyone and reflections were given by a representative from each year group. Dr. Urasa presented awards for outstanding student performance in General Chemistry, Organic Chemistry and Physical Chemistry. There was lots of food to choose from -- curried chicken, greek salad and many other delicious dishes prepared by faculty and staff. Chemistry majors and graduate students supplied drinks and desserts so there was plenty to go around. Dr. Houston gave an interesting talk on her journey from Hampton to UNC, Chapel Hill and beyond and Ms. Blade spoke about her research at Purdue, having met earlier in the day with majors to offer information on Purdue's graduate program. Several current faculty have Purdue doctorates (Drs. Gqamana, Young-Gqamana and Waddell) so there may have been some reminiscing going on. Thanks to all for making another annual dinner a success!
