Jessica Hart

Research Technician

Jessi joined the Zackular lab as a Research Technician in November 2018. She earned her B.A. in Earth and Environmental Science from Temple University in 2017. At Temple, Jessi worked as a research assistant in the laboratory of Dr. Erik Cordes studying anthropogenic impacts to deep-sea corals. Prior to this, she studied plant-pollinator interactions of a local native wildflower affected by habitat fragmentation with Dr. Rachel Spigler. Jessi is from Reading, Pennsylvania.

Orlaith Keenan

Research Technician

Orlaith graduated from the University of California, Santa Barbara in 2019 with a B.S. in Microbiology. As an undergrad, she worked at Apeel Sciences, a company that develops edible coatings to extend the shelf life of fresh produce. While at Apeel, she isolated and identified fungal pathogens from moldy fruits and screened plant-derived molecules for antifungal activity against the pathogens. Orlaith is excited to start working with gut bacteria and learn about the various ways they impact human health.


Postdoctoral Research Fellows

Arwa Abbas Blurb Photo V1.png

Arwa Abbas, PhD

Postdoctoral Research Fellow

Arwa is a postdoctoral researcher hailing from the Bushman Lab at the University of Pennsylvania. She graduated from Rutgers, the State University of New Jersey in 2012 with a B.S in Biotechnology and a minor in Biochemistry. While her undergraduate research focused on environmental bacteria, she studied the human viral microbiome in graduate school and successfully defended her thesis (without even needing the aid of a lightsaber) in the spring of 2019. Now, she’s eager to get back to bacteria in the Zackular lab! When she’s not at the bench (sometimes even then), she is often doodling.


Graduate Students

Joshua Soto-Ocana

Graduate Student (CAMB-CB)

Every story has a beginning and Josh’s started in Puerto Rico. He graduated from the University of Puerto at Mayagüez in 2018 with a B.S. in Industrial Microbiology, a B.S. in Biology, and a minor in Biochemistry.  While his undergraduate research was focused on organic chemistry and biochemistry, he was always very passionate about cancer and microbiology. That’s why he decided to join the Zackular lab and the Cancer Biology graduate program at Penn. Josh is eager to investigate the metabolic crosstalk between the host, microbiota and immune system in colorectal cancer. When he is not at the bench he enjoys going to the beach, chasing waterfalls, biking, and working out.

Alexander B. Smith

Graduate Student (CAMB-MVP)

Alex is a graduate student in the Microbiology, Virology, and Parasitology program. He comes from a small town in central PA and graduated with a B.S. in Biochemistry and Molecular Biology from Penn State University. During his undergrad, he studied the genetic basis for modifications made to E. coli lipopolysaccharide in the lab of Dr. Timothy Meredith. He’s excited to get his hands in the anaerobic chamber and start deciphering the interspecies interactions between C. difficile and Enterococcus. When he’s not in lab, Alex enjoys cooking, working out, and exploring Philly.

Mauricio Alvarez

Undergraduate

Mauricio hails from Colombia and he joined the Zackular Lab as an undergraduate research assistant in the winter of 2019.  Mauricio is studying Biology and Chemistry at the University of Pennsylvania and is planning on pursuing an MD-PhD after graduation. When he is not studying or in lab, he also “enjoys” his time conducting physical chemistry research, training as a triathlete, or as member of the Penn Equestrian Team.

Research Openings

Graduate students:

The Zackular Lab is looking for excited and motivated graduate students to join the team. If you are a current member of the Immunology Graduate Group (IGG) or the Cell & Molecular Biology Group (CAMB), reach out to Dr. Zackular directly to discuss rotation and thesis projects. Prospective students interested in the Zackular Lab should strongly consider applying to the CAMB or IGG programs at the University of Pennsylvania.

Postdoctoral fellows:

We are currently looking for highly motivated postdoctoral fellows interested in the gut microbiota, host-pathogen interactions, and bacterial pathogenesis. Prospective postdocs interested in clinical, basic, or computational research in these areas of research are strongly encouraged to apply for a position. To apply, contact Dr. Zackular directly with a cover letter, copy of your updated CV, and the contact information of 2-3 references.

Research Technicians:

Research technicians work to maintain the day to day lab operations and have the opportunity to drive independent research projects. Currently, we are not looking for research technicians for the lab, but if you are interested in a research technician position in the future, contact Dr. Zackular directly or visit careers at CHOP for openings.

Undergraduate researchers:

The Zackular lab is committed to giving trainees at all levels the opportunity to gain research experience and receive mentorship. If you are an undergraduate student at the University of Pennsylvania and would like to work in the laboratory, reach out to Dr. Zackular directly. Undergraduate researchers will work along side other trainees in the laboratory and be given the opportunity to develop an independent research project or thesis project.
