Graduate Students

Carlos Medina – 2015 -2020 Carlos studied immune regulation in asthma and other airway inflammatory diseases in the Bollyky Lab. He also had leadership roles in multiple mentorship, minority recruitment, and LGBTQ support programs on campus.  After graduation, Carlos moved to Baltimore where is heading up a diversity and inclusion program at Johns Hopkins.

Payton Marshall – 2015-2020 Payton was a MSTP student  in the Immunology PhD program.   He came into the lab with a strong background in engineering and microfluidics in particular. Payton successfully defended his thesis, sharing his excellent work on pericellular matrix and antigen presentation. Dr. Marshall will now be working to complete his medical degree at Stanford.

Jolien Sweere – 2013-2018 Jolien was amazing. She singlehandedly built up our bacteriophage research program and developed most of the animal models, cell lines, and other tools we use for that work. Her research was published as a first author manuscript in Science.   Jolien is currently working at Charles River Associates on biotechnology consulting.

Maria Birukova – 2014 -2016 Maria was a MSTP and Immunology PhD student.  Maria worked on the role of Pseudomonas and phage in chronic wounds.  She passed away on September 18th during a mountain climbing accident.   Maria is greatly missed by the  Bollyky lab and the Stanford community.

Senior Staff Members

Alana Persaud – 2017-2020 Alana was our lab manager for 3 years.  She came to us after several decades at at HHMI lab in New York .

Robert Manasherob – 2016 Robert was our resident molecular biology expert. He has over 20 years of experience.  Robert  spent a year enhancing the microbiology aspects of our Pseudomonas and phage research.  He is now working on phage projects with our collaborator Derek Amantullah in Orthopedics.

Heather Ishak – 2014-2017 Heather was the lab manager for the Bollyky lab for over 3 years.  Heather was an essential part of the diabetes and bacterial biofilm research in the lab.  She moved on to take a lab manager’s position at the Palo Alto VA.

Ben Falk – Researcher, Staff – 2013-2014 Ben moved from Seattle with Paul to start-up the Stanford Bollyky lab.  We are what we are today because of Ben and Mary’s efforts.    Sadly for us, Ben moved to LA and manages a lab at City of Hope Hospital.


Riya Goel – 2021 Riya worked as our clinical trial coordinator assistant for our Hymecromone clinical trial.  She also helped out in the lab on various experiments.

Stanford Undergraduates

Michelle Bach – 2016-2019 Michelle was a superstar undergraduate at Stanford who was a mainstay of our lab for several years. She worked closely with Jolien Sweere and  developed our wound models.  She is bound for medical school, public health and many, many great things.

Ethan Katznelson – 2013-2016 Ethan was a Bollyky lab regular; he worked in the lab for 3 years while he was an undergratuate student at Stanford.  He worked closely with Jolien Sweere on the Pseudomonas aeruginosa biofilm research.  Ethan is now attending Harvard Medical School.

Jason Yang – 2013-2015 Jason was an undergraduate who spent 2013 working as a lab aid in the Bollyky lab.   Jason worked on wound healing projects as well as diabetes drug treatment studies. He is currently a graduate student in bioinformatics at Stanford.
