Since 2010, I have immersed myself into in entomology and other research areas.

I have found a love and dedication to this realm, and you can find all of my publications here.

​Postdoctoral Research
In 2020 I began postdoctoral research, co-mentored by Professor Brian Johnson at UC Davis and Professor Tim Linksvayer at Texas Tech. I am an NSF postdoctoral research fellow in Biology from October 2020-2023. Our collaborative research is focused on making scalable, reproducible, and transparent bioinformatic pipelines, so that we can use modern genomic techniques to address fundamental questions in evolution. We take a behavioral ecological perspective on the eusocial insects, while also highlighting the importance of complex gene families, taxonomically-restricted loci, tissue-specific gene expression patterns, distributed physiology, and colony-level cognitive processes.

Graduate Research
My PhD thesis research was in the lab of Professor Deborah Gordon at Stanford University. We studied collective behavior in the red harvester ant Pogonomyrmex barbatus. ​My project explored the biology that underlies the regulation of ant colony traits such as collective foraging. I used multiple types of technologies to understand foraging behavior from the perspective of collective decision-making, neurophysiology, ecology, and evolution.

My thesis work and related ant research were published as:
2020, Communications Biology, “Gene expression variation in the brains of harvester ant foragers is associated with collective behavior”. DA Friedman, RA York, AT Hilliard, DM Gordon. 
2020, Analytical and Bioanalytical Chemistry, “Measurement of natural variation of neurotransmitter tissue content in red harvester ant brains among different colonies.". Shin M, Friedman DA, Gordon DM, Venton BJ,

Also we wrote some ant Reviews and Perspective papers

2018,

Undergraduate Research
At University of California, Davis, I primarily worked in the lab of Professor Artyom Kopp, working on the evolution of sexually dimorphic traits in Drosophila. We were exploring how cis-regulatory elements in the genome (enhancers) could change over evolutionary time to create new gene-gene interactions, and how that process could generate morphological diversity. Working with many species of Drosophila was amazing - the lab had lines of flies collected from all over the world, each with something to teach us.

I also worked in the lab of Professor Brian Johnson on honey bees. Honey bees undergo a structured transition between tasks as they age, and we were interested in how gene expression in the brain might be involved in these behavioral transitions. Dissecting bee brains is very relaxing, and served as an excellent introduction to behavioral genetics in eusocial insects. The work with bees was published as "Large-scale coding sequence change underlies the evolution of postdevelopmental novelty in honey bees" in 2015, and provides some interesting work towards understanding the relationship between gene coding sequence changes and tissue-specific gene expression changes.
