Our lab offers opportunities to undergraduates, graduate students and postdoctoral researchers. Undergraduates are able to apply what they have learned in organic chemistry and biochemistry toward active medicinal chemistry projects. Graduate students receive interdisciplinary training including small molecule analog design and synthesis, cell culture, and structural biology. The overall goal is for students to have a well-rounded experience and understanding of small molecule structure-based design and be carry out multiple facets of the process as they move on in their research careers.
Daniel Flaherty, PhD
Dr. Flaherty received a Bachelor of Arts in chemistry from Central College in Pella, IA. He then moved on to earn his PhD in pharmaceutical sciences under the direction of Dr. Jonathan Vennerstrom at the University of Nebraska Medical Center. Following his graduate studies he moved to the University of Kansas and joined an NIH sponsored medicinal chemistry lab under the direction of Dr. Jeffrey Aubé as a post-doctoral researcher and later as a research track faculty. He is now an assistant professor in the Department of Medicinal Chemistry and Molecular Pharmacology at Purdue University with interests in developing small molecule inhibitors using structure-based design for under-explored biomolecular targets. His research focuses on validating novel therapeutic targets for treatment in infectious disease, cancer, and neurodegenerative disease.
