Green Lab

Dr. Green is an Associate Professor of Pediatrics and investigator in the Morgan Adams Foundation Pediatric Brain Tumor Research Program at the University of Colorado.

He did his undergraduate work at Dartmouth College and earned his MD from NYU School of Medicine. He then served as a pediatric resident and chief resident at Children’s Hospital Colorado, followed by fellowship at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, where he worked with Mark Kieran and trained in the labs of Andrew Kung and Stuart Orkin. He then returned to the University of Colorado in 2014, where he was mentored as a junior faculty member by Rajeev Vibhakar, as well as Nick Foreman. 

John holds BS and MS degrees from the University of Utah and a JD from the University of Denver. After distinguished careers in geoscience and law, he became a biomedical researcher, working first with James Ortho at CU-Boulder, and then, since 2015, in the Green Lab. In 2023, he earned his PhD from the University of Colorado Anschutz after completing his dissertation research in the lab.

He has specific expertise with high-throughput analysis and pathway investigation. He is a gifted teacher and leads the hands-on education of trainees in the lab.

Mathew Slade, BA (Research Services Professional)

Mathew earned his BS in Biophysics from Brown University in 2020. He joined the lab in 2022 and has developed expertise with patient-derived cell culture models and combination therapy in PHGG.

Gabrielle Link, BS (Research Services Professional)

Gabby received her BS in wildlife ecology from the University of Maine in 2020. After working as a field research technician at Louisiana State University, she joined our lab in 2022, where she leads our work on mouse models of PHGG.

Charlotte Feddersen, MD, PhD (Clinical Fellow/Post-Doc)

Charlotte received a BA from Grinnell College in 2012 in Biological Chemistry and her MD, PhD from the University of Iowa in 2020. She then moved to Colorado to complete a Pediatric Residency at Children's Hospital Colorado (CHCO) in 2023 and stayed to become a Pediatric Hematology and Oncology Fellow at CHCO. She is also completing her post-doctoral research with a specific focus on cellular therapy for pediatric high-grade gliomas and collaborates closely with researchers at Colorado State University College of Veterinary Medicine on a canine comparative oncology clinical trial.

Alyssa Powell, MS (PhD Student, Cell Biology, Stem Cells, and Development Program)

Alyssa earned her BS in Biomedical Engineering from the University of California, Davis and her MS in Stem Cell Biology and Regenerative Medicine from the University of Southern California. She is currently a PhD student in the Cell Biology, Stem Cells, and Development program at CU Anschutz, where she is conducting her thesis research in our lab and the lab of our collaborator, Dr. Santos Franco. Her work focuses on developing and using an in utero electroporation mouse model to investigate pediatric high-grade gliomas. A fun fact about Alyssa is that she was a competitive swimmer for 15 years.
