Lab Members



PBollykyPaul Bollyky, MD, PhD – 2013

The fearless leader of the matrix immunology research army.   Dr. Bollyky is an Assistant Professor in the School of Medicine Division of Infectious Diseases and also the Department of Microbiology and Immunology.  Furthermore, he is a faculty member in the Stanford Immunology Program.

Paul is from Stamford, CT and went to college at Columbia University in New York City.  He did his Ph.D. at Oxford and his M.D. at  Harvard.  He did medical internship and residency at  Brigham and Women’s Hospital and then Infectious Disease fellowship at the University of Washington.  He completed a post-doctoral fellowship under Dr. Jerry Nepom at the Benaroya Research Institute.  He was appointed to the Stanford  faculty in 2013.



Alana Persaud – 2017

Alana joins the Bollyky lab after 16 years with HHMI under Dr Hermann Steller in The Strang Laboratory of Apoptosis and Cancer Biology at The Rockefeller University.



mike_kratchovilMike Kratochvil – 2016

Mike is a shared post-doc between the Bollyky lab and the Heilshorn lab at Stanford who is straddling the line between immunology and bio material engineering.  Mike is a Chemistry PhD from University of Wisconsin and we are excited to see how his skills can challenge our thinking about immunology and our hyaluronan projects.

LizBurgenerElizabeth Burgener, MD  -2016

Liz is an MD and a pediatric pulmonology fellow who is interested in pseudomonas and Cystic Fibrosis.   In our lab, Liz is studying how Pf phage contribute to the disease burden in CF.   She uses qPCR to correlate sputum phage counts with clinical outcomes in CF.



HedwichHedwich Kuipers2014

Hedwich straddled the Bollyky lab and Steinman lab for several years but is now a full-time Bollyky lab researcher.  She is investigating autoimmunity from a neuronal background with a research focus in Multiple Sclerosis.   Hedwich is also researching IL2 and heparinase.


Nadine Nagy – 2014

Nadine  finished her postdoctoral research at Benaroya Research Institute in Seattle and then moved to join the Bollyky lab.  Her research is focused on the role of hyaluronan during development and progression of type 1 diabetes (T1D).  She is helping to develop the drug 4-MU for clinical trials.


Dr_Gernot_Kaber_2013Gernot Kaber – 2014

Gernot has joined the Bollyky lab after a working  for the Benaroya Research Institute.   Gernot is involved in practically every ongoing research project in the Bollyky lab, because he knows how to do EVERYTHING.



JolienJolien Sweere – 2013

Jolien Sweere is a PhD candidate in Stanford University’s Program in Immunology. Her work currently focuses on elucidating the molecular mechanism behind the immune suppression observed in chronic biofilm infections of the pathogen Pseudomonas aeruginosa. Jolien uses flow cytometry, fluorescent microscopy, gene expression analysis and other techniques to investigate how individual biofilm components work together to suppress dendritic cell activation and antigen presentation. The ultimate goal of her research is to explore and develop therapeutic strategies to disrupt this biofilm-mediated immune inhibition.

Growing up in the Netherlands, Jolien pursued a BSc degree in Liberal Arts & Sciences at University College Utrecht, graduating summa cum laude in 2009. She obtained an MSc degree in Infectious Diseases and Immunology from Utrecht University in 2011. During her Master’s program, she worked in the lab of Rob Willems at University Medical Centre Utrecht, Utrecht, the Netherlands, and the lab of Vijay Kuchroo at Brigham and Women’s Hospital, Boston, MA, USA. Before starting her PhD program at Stanford University, Jolien was a visiting student researcher in the lab of Eugene Butcher at the Veteran’s Affairs Hospital in Palo Alto, CA, USA.

CarlosWebsiteCarlos Medina – 2015

Carlos Medina is a PhD candidate in the Immunology program at Stanford University School of Medicine. His work currently focuses on understanding the mechanisms of long-term tissue-specific tolerance in allergic asthma. In tandem, he is working on ways of utilizing extracellular matrix proteoglycans to promote these tolerogenic lung responses, targeting the immunological root causes of allergic asthma. Carlos is a Ford Foundation fellow and a Stanford DARE fellow and serves the community through his role as President of the Biomedical Association for the Interest of Minority Students.

PaytonPayton Marshall – 2014

Payton is a MSTP student and also in the Immunology PhD program.  During the summer in 2014, Payton rotated in Bollyky lab where his research focused on airway hypersensitivity. He joined the Bollyky lab in 2015 and is working on how 4-Mu affects antigen presentation.  He is also investigating 4-Mu impacts on organ transplants.



Graham Barlow – 2017

Graham is a second year grad student in the Immunology program.  He is co-mentored by Garry Nolan and is working on the using high-dimensional imaging to study how cells coordinate in their native tissue contexts. He is especially interested in tissue architecture and how this organization induces and breaks tolerance, especially over long time periods.



Medeea Popescu -2017

Medeea is a first year Immunology grad student rotating in the lab for the Fall quarter. She is working with Jolien to study immune suppression by Pf phage in the context of Pseudomonas aeruginosa infection.





Michelle Bach– 2017

Michelle is a junior majoring in Health Sciences at Stanford.  She joined the lab in early 2017 to help with the Cystic Fibrosis bacterial and phage quantification.  During the summer, Michelle earned a BioX summer grant to pursue more phage and Pseudomonas biofilm related research.
