Research Projects/Interests


Cardiovascular disease (CVD) is the number one cause of death in American men and women.  One of the major factors in heart disease is blood cholesterol, which is carried by lipoproteins.  One of the most commonly used risk factors for heart disease is the serum level of HDL (high density lipoprotein) and LDL (low density lipoprotein).  High HDL and low LDL levels are correlated with reduced risk for heart disease.  HDL lowers the risk for CVD because it elicits the removal of cholesterol from cells in peripheral tissues.  This process is facilitated by the major protein in HDL, apolipoprotein A-I (apo A-I).  Our lab explores the structure-function relationships of apo A-I in humans and in other organisms. More recently, and in collaboration with several apolipoprotein A-I researchers, we have been exploring the properties of amyloid-forming variants of apoA-I. A large number of Sac State students (more than 80) have worked on apo A-I in my laboratory. Most of these students have gone on to PhD programs, jobs in industry, or medical or other professional schools. Students interested in participating in this research should contact me in person (check my current office hours). I welcome master's students as well as undergraduates at all levels. I also work with students from both the Chemistry and Biological Sciences departments. Since the training students receive in my lab requires a lot of my time, I also require a one-year commitment so that sufficient progress can be made for a research presentation at a regional or national meeting. For more information about our research, please make an appointment to come and see me or contact me at robertslm@csus.edu.

CURRENT STUDENTS (Degree path in parentheses)

Roman Ishchuk (MS Chemistry, Biochemistry concentration). Roman died last year in an accident. He was examining the effect of detergents on fibril formation in Apo A-I. He worked for Agrinos, a plant biotechnology company in their research division. He was an extraordinarily kind and generous person and we will miss him tremendously.

Eric Herrera (MS Chemistry, Biochemistry concentration) Eric is examining the use of case studies in a chemistry course for pre-nursing students and plans to teach college level chemistry after he graduates.

Thao Tran (MS Chemistry, Biochemistry concentration) Thao is examining the effect of different pH's on the stability of amyloidogenic apoA-I.

Roman Demchuk (BS, Biological Sciences, Clinical lab sciences concentration) Roman is investigating the kinetics of acid-induced aggregation of amyloidgenic ApoA-I. He is planning on going to medical school.

Tim Lee (MS Chemistry, Biochemistry concentration) Tim received his Bachelor's degree in Biochemistry last year and is now beginning a thesis project in the lab.

Nancy Nguyen (MS Chemistry, Biochemistry concentration) Nancy completed her Bachelor's degree in Biochemistry last year and is now beginning a thesis project in the lab.
