Iliana M. Restrepo, Clare Boothe Luce Assistant Professor of Chemistry (Program Chair)

Description

The Chemistry/Biochemistry Program gives students a solid foundation in analytical, organic, and physical chemistry, and emphasizes the central roles that chemistry plays in biology and the global environment. The biochemistry major provides additional insight into the relationship of chemistry to living organisms. Throughout the programs in chemistry and biochemistry, students acquire the knowledge and skills necessary to be successful in fields in which women are still underrepresented, and they gain the opportunity to explore options such as graduate school, medical school, or employment in the industrial sector.

Students in the College of Arts and Sciences may elect to pursue either a B.A. or a B.S. degree in chemistry or biochemistry. A major and a minor are offered in both fields.

Prospective science majors should be aware that most upper-level science courses are offered every other year, and it may not be possible to complete the requirements for the major in one academic year, regardless of the number of credits transferred in. It is suggested that any student transferring in with more than 64 credits who plans to major in chemistry or biochemistry meet with a chemistry faculty member before registering for any courses in order to plan an appropriate program and to determine how long it will take her to complete the degree requirements.

Students should note that MATH 123 is a prerequisite for (or can be taken concurrently with) the Fundamentals of Chemistry course.

Program Policies

Advanced Placement: A grade of 4 or 5 on the Chemistry AP exam will be accepted in lieu of CHEM 111.

CLEP Policy: A satisfactory score on the CLEP exam in general chemistry will be accepted in lieu of CHEM 111.

Grades in Major Courses: Students are required to earn a grade of "C" (2.0) or better in all courses counted to fulfill requirements for the major.

Pass/No Pass: The pass/no pass option is not acceptable for courses taken to fulfill major or minor requirements.
Senior Assessment: The senior assessment in chemistry or biochemistry consists of a written report and oral presentation relating to the work done in CHEM 491 or 497.

TELL Policy: Because of the importance of the laboratory experience, TELL credits may not be applied toward the chemistry major.

Transfer Credits: All chemistry and biochemistry majors are required to complete successfully a minimum of 15 credits in chemistry at Trinity College. With the approval of the program chair, courses in biology or other relevant areas of study offered at Trinity may be used to satisfy the 15 credit requirement. All chemistry/biochemistry majors must take NSCM 499 Divisional Seminar at Trinity (NSCM 499 may count toward the 15 credit hours taken at Trinity). Biochemistry majors must take CHEM 431, 432 Molecular Biochemistry I and II at Trinity.
