Phylis Hétié assists the firm in biotechnology patent prosecution. She has extensive knowledge in the areas of stem cell biology, genetics, biochemistry, cellular and molecular biology, high throughput screening, and drug discovery.

Prior to joining Wolf Greenfield, Phylis interned and consulted at AvroBio Inc., and conducted postdoctoral research at Harvard University in the Department of Stem Cell and Regenerative Biology in Cambridge, MA. As a postdoctoral fellow, she performed small molecules testing, using stem cell-derived motor neurons to identify new and potent drug candidates to treat the devastating disease spinal muscular atrophy or SMA.

As a graduate student in the Department of Cell Biology at Johns Hopkins University, Phylis investigated changes that happen within the adult Drosophila testis stem cell niche when it is subjected to insults. Her study led to the identification of niche cells as the source of new somatic stem cells and new niche cells, when the somatic stem cells are fully ablated in the adult testis. These studies were presented at local and international conferences, and published in the prestigious journal Cell Reports.

Additionally, Phylis was a research assistant in the laboratory of Dr. Andrew Feinberg at Johns Hopkins University in Baltimore, MD. She also has experience in tutoring and mentoring undergraduate students.
