Former Graduate Students

Josue Duque (Fall 2019-Spring 2022)

Josue was an M.S. Biology student examining the population genetics of Palmer amaranth (Amaranthus palmeri) a weed of growing concern in the Californian agricultural community.  He compared individuals found in agricultural and wild environments to better understand the underlying genetic difference between Palmer native to the southern regions of the state and the emerging populations in the San Joaquin Valley. As a Ph.D. student in the QSB program at UC Merced, he is continuing to study population genetics/phylogenetics and generating new bioinformatics data analysis tools and methods.

Alexander Lopez (Fall 2018-Spring 2022)

Alex worked on a M.S. Biology project on waterhemp (Amaranthus tuberculatus), an important Midwestern agricultural weed that has recently begun to show up in the Central Valley.  He used genotyping-by-sequencing to investigate the California invasion of this species.  He started a PhD in the Crop Science Department at the University of Illinois in Fall 2022. Post-PhD, his career goals are to obtain a job in the broad field of genetics and bioinformatics, possibly in an agricultural industry position.

Reece Riley (Fall 2018-Spring 2022)

Riley’s MS Biology project was a phylogeny of the genus Helianthella, the little sunflower, using genetic sequencing to assess the relations within the genus, which has been mostly ignored since the 1950s. They have also been working in the Fresno State Herbarium since they were an undergrad, first digitizing herbarium specimens, but more recently aiding in the transfer of entries and images to the new database and intake of new physical specimens, and georeferencing. They started the QSB PhD program at UC Merced in Fall 2022. 

Christopher Bivins (Spring 2019-Spring 2021)

Chris studied the ecological interactions between plants and fungi in forest ecosystems using mycoheterotrophic (MH) plants as a model system. MH plants are plants that have evolved to completely lose the ability to photosynthesize. Instead, their roots are colonized by particular species of fungi that create a network of connections to other plant roots throughout the soil. Sugars produced by nearby photosynthetic plants travel through roots into the fungal network, and these sugars are then given to MH plants by their fungal symbiotic partners. His MS project (coadvised by Dr. Alija Mujic) specifically focused on whether MH plants are beneficial or detrimental to the species involved in forest fungal networks. Chris is currently pursuing a Ph.D. in QSB at UC Merced and continues to study ecological interactions between plants and fungi.

Romy Lum (Spring 2018-Fall 2020)

Romy tested populations of Palmer amaranth from the native range (southwestern U.S.) and the invaded Central California range for resistance to different chemical classes of herbicides, include glyphosate (RoundUp), acetolactate synthase (ALS) inhibitors, protoporphyrinogen oxidase (PPO) inhibitors, and glufosinate.  His approach combined greenhouse assays with genetic PCR and qPCR assays and sequencing.  His career ambition is to work in forensic research.

Adam Avila (Spring 2017-Fall 2019)

Adam worked on a project comparing the composition of endophytes between a parasitic plant (Cuscuta campestris) and one of its host plants (Helianthus annuus) in the Central Valley. This project was coadvised by Dr. John Constable. He received a B.S. in Biology from Fresno State in Spring 2017, and graduated with an M.S. in Biology in Fall 2019.  Adam is currently working as a COVID-19 contract tracer for the Fresno County Department of Public Health, while he applies to medical schools.

Priyanka Chaudhari (Spring 2017-Fall 2018)

Priyanka conducted research on the genetic basis of glyphosate herbicide resistance in hairy fleabane (Erigeron bonariensis) for her M.S. in Biotechnology.  She used techniques such as RNA extraction and gel electrophoresis, PCR, cDNA synthesis, and qPCR, to examine the possible upregulation of several candidate genes that may be involved in non-target site resistance to glyphosate in this species.  Priyanka now works for MolecularMD as a Clinical Medical Technologist in Portland, OR.

Ankit Pathak (Fall 2015-Spring 2017)

Ankit was the first M.S. student in the Waselkov lab, in the Biotechnology program at Fresno State.  His project was a greenhouse common garden experiment testing the fitness costs of glyphosate resistance in hairy fleabane, in well-watered vs. drought conditions.  He worked very hard and collected a plethora of data, which awaits replication for publication.  After graduation, he obtained a position in medical data analysis with the company Adaptimmune in Philadelphia, PA.

 

Former Undergraduate Students

Pawanpreet Gill (Summer 2018-Spring 2021)

Pawan, along with partner Savneesh Athwal, worked on a project regarding the native California species Phlox speciosa. They tested out microsatellite markers to better understand the genetics and taxonomy of this species. The purpose of this project is to analyze the different populations across a geographic range of Phlox speciosa and determine whether there are subspecies and genetic differences. Pawan also imaged Fresno State Herbarium specimens and learning how to process them to upload to the online database. She earned a B.S. in Biology from Fresno State in Spring 2021.  Her career goal is to go to medical school to pursue a career in medicine.

Savneesh Athwal (Summer 2018-Spring 2021)

Sav worked alongside Pawanpreet Gill on their project regarding Phlox speciosa. She worked on PCR and gel electrophoresis for 3 different microsatellite markers which will help interpret the genetic differences in the populations of Phlox. She also worked on analyzing data we have completed and sent to the genomics company Laragen.
