I learned about research while working in Kay Holekamp's lab as an undergraduate at Michigan State University. After a short stint as a zookeeper, and a couple field jobs, I went to graduate school at UCLA. My PhD research was co-advised by Peter Nonacs and Bob Wayne, where I made the transition from carnivores to bees. I followed this with a post-doc in Gene Robinson's lab at UIUC, where I got into comparative genomics. I started my lab at Utah State University in 2014. I see mentoring students and building a supportive lab environment as one of the most important (and favorite) parts of my job. 

CURRENT LAB MEMBERS (alphabetical)

Mira C. Henderson, Undergraduate researcher
She/her/hers

I earned my Associate of Arts degree in Spanish Language and a CTE certificate in biotechnology in 2023. Through my biotechnology training and experience in other research labs, I was introduced to scientific research and developed an interest in problem solving and deductive reasoning. I am currently pursuing a bachelor's degree in Biological Engineering with a minor in Mechanical Engineering at Utah State University and expect to graduate in 2027. 

While at USU, I became involved in synthetic biology, biological engineering and bee research. This experience has given me the opportunity to build my research skills while contributing to work with meaningful ecological and environmental applications. Working with bees has broadened my understanding of how research can be applied and has given me firsthand experience with the research process, from experimental design to data collection and analysis.

I earned my B.S. in Biology from Tufts University in 2018, where I was first captivated by the study of bee behavior. After graduating, I worked as a field technician for a number of coastal ecology and sea turtle conservation projects around the United States and the Virgin Islands. In addition to gaining a breadth of fieldwork experience, these projects gave me an appreciation for climate-focused research, which I am excited to build on as I return to bee behavior in my graduate research. 
 
In the Kapheim Lab, I am studying the effects of global warming on mechanisms of bee sociality, using the socially polymorphic sweat bee, Halictus rubicundus. I am also a fellow in the NSF-funded Climate Adaptation Science program at Utah State University, where I am working with a cohort of graduate students to design integrative research that will contribute to climate resiliency in the Interior West.

Matt Del Grosso, Ph.D. student
I received my B.S in Biology with minors in Chemistry and Psychology from Salisbury University in 2012. Under the advising of Kim Hunter and Ryan Taylor, my undergraduate research focused on sexual selection, population genetics, and behavioral genetics with interests ranging from the communication of genetic information via sexual signalling in Pseudacris crucifer (spring peepers) to RNAi knockdown of behaviorally significant genes in C. elegans and population genetic analyses of Cyathea divergens (a Honduran tree fern). I am also  interested in environmental conservation, which led to about a year of service in Americorps Conservation Corps mainly focused on removal of woody invasives in riparian zones and restoration of sage grouse habitat in Utah and Nevada, respectively.
In the Kapheim lab at USU, my research interests broadly involve elucidating the evolutionary significance of phenotypic plasticity (especially in relation to social behavior in Hymenoptera) and the regulatory mechanisms (genetic, transcriptional and neurobiological) that bring about this phenotypic plasticity.

 In Memory of Matthew S. Del Grosso (9/28/1990 – 5/21/2015)

Our hearts are heavy, but our spirits are brimful as we honor the memory of Ph.D. student Matt Del Grosso. Matt was only in the first year of his Ph.D. program at Utah State University, but his potential as a scientist was abundantly clear and the impact he made on our lives is immeasurable.

At the time of his tragic accident, Matt had only been back in Logan for ten days. We had just completed an extremely successful three month field season in Panama, where Matt had developed an original research program that integrated his interests in sexual selection, neurobiology, and molecular biology in the pursuit of understanding how social behavior evolves in bees. During the field season, Matt demonstrated his ability to juggle field and lab work while brainstorming new ideas and troubleshooting experimental design. He even developed a new research agenda of his own, implemented new experiments, and wrote a fellowship proposal in the midst of all of his field work.

Matt absolutely loved being in the tropical forest. We looked forward to an animated and exuberant “show and tell” of the discoveries Matt had made while canvasing the forest for bee nests each day. He even spent many of his “days off” in the forest – an opportunity most of the rest of us took to soothe our chigger and tick bites. Matt also made sure to savor all the new experiences the rest of Panama had to offer. He attended Carnival, swam in bioluminescent lagoons, snorkeled in Caribbean reefs, and developed close relationships with other field biologists from around the globe.

Matt never ceased to find wonder and excitement in his experiences, regardless of his surroundings. He relished in the adventures that Utah’s unique landscape had to offer, the promise of fossils that had yet to be found, and the bounty of B-movies and zombie books that offered journeys of the type science and nature did not provide. In this way, Matt’s spirit captured all of us. He was somehow both fully present in the moment and excitedly anticipating the future with seemingly endless passion and enthusiasm. His open-mind, positive outlook, and kind heart seemed to be contagious, for Matt’s presence consistently brightened everyone’s day.

We were unbelievably lucky to have shared a small portion of Matt’s life with him. His legacy will live on in our lab as we remind ourselves to seek out and savor the everyday adventure that life and scientific discovery have to offer.
