Brief Bio:
Dr. Doerder earned the Ph.D. in Cell Biology from the University of Illinois - Urbana/Champaign. Following a year of post-doctoral research at the University of Iowa, he joined the faculty of the University of Pittsburgh.  In 1981 he joined the faculty of Cleveland State University.

A geneticist, he has taught a wide variety of courses, including cell biology, biochemistry, molecular biology, general biology, and non-majors biology.  He has directed the research of many M.S. and Ph.D. students.  Three of his Ph.D. advisees are on the faculties of local colleges.
 
Research Interests:
My lab currently focuses on the population genetics and biogeography of Tetrahymena thermophila and the ~40 other members of the genus Tetrahymena.  We combine field studies and molecular techniques to study population structure, distribution, and biogeography.  

My early research focused on regulation of genes encoding a major cell surface protein, the immobilization antigen.  Using mutagenesis, my lab group identified regulatory genes and extended the number of gene families encoding immobilization antigens.  Today, we use bioinformatic procedures and the T. thermophila genome sequence to study these genes. In the mid-1980s I discovered natural populations of T. thermophila in western PA. A rare species, T. thermophila and members of the genus were little studied in natural populations.  My lab group has studied mating type frequencies, immobilization antigen polymorphisms, and population structure of T. thermophila.  In addition, we are collecting water samples to determine the distribution of other members of the genus using DNA barcodes. The results are relevant to fundamental questions in population biology and biogeography.
