Cell Biology: Dr. Visviki is investigating the dynamic mitochondrial morphology of Chlamydomonas acidophila and Chlamydomonas applanata during the cell cycle, its relation to the physiological processes in the cell, as well as its adaptive significance for the species.
Environmental toxicology: Previous studies have focused on the effects of acidification and heavy metals on the growth and ultrastructure of aquatic organisms. Currently, Dr. Visviki collaborates with Dr. Michael Judge and Dr. John Mahony (Deptartment of Environmental and Civil Engineering at Manhattan College) to determine sediment quality criteria for arsenic for which such data are lacking.

External Research Support:
Dr.
Visviki received a federal EPA Superfund grant for
hazardous substance research as principal investigator,
with co–principal investigator Dr. Michael
Judge (“Development of Arsenic Sediment
Quality Criteria using Equilibrium
Partitioning”). Dr. Visviki and Dr. Judge
have extensive experience with toxicological and
ecological investigations, and the joint research
capability of Mount Saint Vincent and Manhattan College
will play a critical role in the study. As part of
the four-year grant, six undergraduate students from the
Biology program will participate
in the project each year, gaining
intensive research training,
mentorship, and advisement.
