Alyssa is a Cleveland native who started at Case Western Reserve University in July of 2023. Alyssa completed her bachelor’s degree in biology from the College of Wooster in 2020 and her master’s degree in biological sciences from the University of Cincinnati in June 2023. As an evolutionary geneticist, she loves learning about how organisms adapt to their environment, how this impacts their genome, and the impact on the expression of genes. Currently, Alyssa is using a new technique to characterize the gene expression of single cells in the oral microbiome to better understand the microbial interactions that contribute to aggressive periodontitis. Outside of the lab, Alyssa spends her time knitting, crocheting, and taking care of her plants and fish.

"The goal of the present study is to begin to define the structure and functional organization of the olfactory bulb in A. mexicanus, and to begin to understand how it was transformed via cave adaptation."

Meet Mathilda Mommersteeg, keynote speaker at the 1st GERMAN FISH MODEL RESEARCH MEETING

Her recent work has highlighted the role of circadian rhythms, the adaptive immune response, and metabolic switches in enabling cardiomyocyte proliferation and re-differentiation.

“These studies establish hypoxia as the driver of heart asymmetry and reveal a mechanistic connection between the hypoxic cave environment and the evolution of a novel trait.”

A balanced circadian glycolytic rhythm drives cardiomyocyte cell cycle progression during fish heart regeneration | Gennaro Ruggiero Did you know that our circadian clock—the internal rhythm that regulates our sleep-wake cycle—also plays a crucial role in heart regeneration? Most people don’t, and that’s exactly why I’m excited to ...

New work from the lab! Cellular processes key for successful heart regeneration occur at specific times over 24 hours and disturbing these day-night rhythms affects cardiomyocyte metabolism, cell cycle and regeneration.

Back from the Cavefish Retreat — amazing people, gorgeous location, great science, and a strong community! 🐟✨

The future looks bright for the #cavefish field!

Dark ages: Genomic analysis shows how cavefish lost their eyes In a new study, Yale researchers used genomic analysis to show when cavefishes lost their eyes, which provides a method for dating cave systems.

Genomic analysis shows how cavefish lost their eyes [via Yale Uni] 🧪👩‍🔬👨‍🦯🐟🏳️👀

"researchers developed a sort of mutational clock that allowed them to estimate when each species began losing their eyes."

The #Ozark #cavefish is pinkish-white and reaches a maximum length of 2 inches. The head is flattened, and it has a slightly protruding lower jaw. The fish has no pelvic fin. It has only rudimentary eyes and no optic nerve. The Ozark cavefish lives only in caves.
