Lab Members





Dr. Margaret Frank
Principle Investigator
Margaret is a molecular plant biologist who is broadly interested in understanding how multicellular organisms communicate across tissues and organ systems, and applying this knowledge towards sustainable crop production. Margaret joined Cornell's School of Integrative Plant Science (SIPS) in July 2018. Prior to moving to Cornell, Margaret was an NSF PGRP Postdoctoral Fellow at the Donald Danforth Plant Science Center in St Louis, MO, where she studied the dynamics of graft junction formation and graft-transmissible RNA movement.
Margaret earned her PhD at Cornell, working with Mike Scanlon on the evolution of shoot meristem patterning in early land plant lineages.
When she's not doing science, Margaret loves to run, travel, and drink coffee.
Michelle Heeney

Ph.D. Student
Michelle is a PhD student in the Frank Lab and the Roeder Lab. She works on dissecting the underpinnings controlling and influencing long distance mRNA movement. Michelle graduated from the University of Massachusetts with two B.S.' one in biology and one in math with a concentration in statistics. Her undergraduate thesis work focused on floral morphology in grasses, under the guidance of Dr. Madelaine Bartlett.
Michelle also worked in the biotech industry at the startup company Inari Agriculture where she developed her skills of plant transformation and bioinformatics.
Outside of the lab Michelle has a passion for film photography and fine art.
Brandon Williams
Ph.D. Candidate

Brandon is a Ph.D. student in the Frank Lab. He is working on engineering a biofluorescent reporter system in tomatoes that would alert famers to nitrogen and phosphorus-deficient soil conditions by performing a “three-step hijack” of the endogenous c-terminally encoded peptide (CEP) system.
His alma mater is the State University of New York (SUNY) at Cortland where he majored in Conservation Biology and minored in Chemistry.
His undergraduate research focused on elucidating the symbiotic relationship between angiosperms and pink-pigmented facultative methylotrophic (PPFM) bacteria.
Elise Boisevert
Ph.D. Candidate
Elise is a PhD student in the Frank lab where she works to shine light on the inner workings of grafted plants. She studies what is happening on a cellular and molecular level as the plant works to heal and join together. Elise started in the Frank lab during her undergraduate at Cornell. Her undergraduate work included a focus in rootstocks and root architecture, and in heterografting solanaceous plants to track mRNA movement.
Outside of the lab, Elise enjoys kayaking, hiking, and hanging out with her cute dogs.

Weiwei Chen
Post-Doctoral Researcher
Weiwei is a post-doctoral researcher in the Frank lab. She’s working on mobile signals from roots to shoots in Arabidopsis.
Weiwei got her Ph.D. in Plant Sciences and Biotechnology from the Universitat Autònoma de Barcelona - Center for Research in Agricultural Genomics.
Outside of the lab, Weiwei enjoys watching films, finding good restaurants, and shopping.


Tian Gong
Post-Doctoral Researcher
Tian is a post-doctoral researcher in the Frank lab. She’s working on grafted tomato production under high tunnel conditions.
Tian got her Ph.D. in Horticultural Sciences from the University of Florida.
Tian is known to enjoy exploring Ithaca and eating Cornell dairy ice cream in her free time!


Noor AlBader
Post-Doctoral Researcher
Noor broadly studies the transcriptional response to abiotic and biotic stressors in plants. Her work has encompassed staple crops such as rice, to novelty organisms such as chia and the beaver. Her genomic work has also led her to work on date palm and wild relatives of rice, with a focus on adaptation to desert and costal regions, respectively, at the Center of Desert Agriculture (KAUST).
She completed her PhD (2019) in the Molecular and Cellular Biology Program at Oregon State University (OSU). She is now a post-doctoral researcher, co-hosted by the Frank and Nelson labs.
Vesna Bacheva
Post-Doctoral Researcher
Vesna is a postdoc who is working on developing new technologies and methods to study vasculartransport in plants. She is co-hosted by the Frank and Stroock labs and is supported by the SwissNational Science Foundation and the Kavli Institute at Cornell.Vesna holds a PhD in mechanical engineering and has received training from EPFL and IBMResearch in Switzerland, as well as Technion in Israel. In her free time, Vesna enjoys biking and yoga.
Sam Yanders
Ph.D. Student
Sam is a PhD student in the Frank lab where she studies the mechanisms that regulate graft compatibility. She received her B.S. in Plant Sciences with emphases in Biology, Horticulture, and Crop Sciences from the University of Missouri. Her undergraduate research focused on the characterization of genes related to ATP stress signaling in the lab of Dr. Gary Stacey, as well as teaching undergraduate courses under the guidance of Dr. Mary Ann Gowdy.
In her free time, Sam enjoys kayaking, cooking, playing video games, spending time with friends, and making her dog wear funny clothes.

Guinevere Goldberg
Scientist in training
Gwenny joined the lab in November 2019. Since then she has provided her expertise in tomato taste-testing. She can be found joining Margaret in meetings, stomping in puddles, or enjoying school.

Annabel and Graham
Scientists in training
Annabel and Graham joined the lab in June 2024. They are preparing for fruitful careers in field research
