Dr. Megan Meuti, Principal Investigator. I graduated from OSU with my PhD in 2014. My dissertation research suggested that circadian clock genes regulate diapause initiation in the Northern House Mosquito, and formed the basis for one of the major lines of inquiry of my lab. I am a passionate educator, and teach graduate level courses on insect physiology and undergraduate courses for non-science majors. I also greatly enjoy sharing my passion for science with all audiences through educational outreach. When I am not playing with bugs in the lab, I am generally at home playing with my four young children. I also  like to bake for lab meetings and read for pleasure.


Lydia Fyie, PhD student (August 2018 – present):  I attended Kalamazoo College, and graduated magna cum laude with a B.A. in biology and theatre arts. As an undergraduate, I performed summer research at Stone Lab with researchers from The Ohio State University looking at the distribution of invasive crayfish in the western Lake Erie basin. I joined the Meuti Lab in the fall of 2018, where and am co-advised by Dr. Mary Gardiner. My research focuses on the effects of urban landscapes on mosquito seasonal responses. Aside from biology, I enjoy participating in the performing arts and act in community theatres.


Dr. Alden Siperstein, Research Associate (August 2019 – present): I graduated from OSU with a B.S. in Biology and an Entomology minor. After graduating, I worked for Dr. Susan Jones as a lab assistant for a year, contributing to insect husbandry and data collection for her studies. I received my PhD from Dr. Meuti in August of 2023 by studying various components of biting, and have been working as her research associate since September. I maintain the laboratory and the insectary and assist my coworkers when possible. When not working, I am probably cooking or baking.


Matthew Wolkoff, PhD student (August 2020 – present): I earned my M.Sc. in Biology from the University of Texas at Tyler in 2018 where I investigated the population and phylogenetic structure, demographic history, and ecological niche of the sand fly Psathyromyia shannoni. I joined the Meuti lab in the fall of 2020, and am working to establish a transgenic Culex pipiens to investigate the molecular mechanisms underpinning seasonal diapause. When not in the lab, I enjoy gardening, woodworking, and cleaning algae out of my aquaria.


Hannah Dehus, PhD Student (October 2021 – present): I graduated from OSU with a B.S. in Biology with an entomology minor in 2021 and have served in The Ohio Army National Guard since 2017. I  am studying the seasonal characteristics of overwintering Anopheles mosquitoes in central Ohio. I have also assisted in graduate student research projects and cared for the lab’s Culex pipiens colony. Outside the lab, I have worked for Franklin County Public Health to assist with mosquito and West Nile virus surveillance. I am passionate about improving the health of communities that suffer from vector-borne disease. I enjoy traveling, hiking, camping, and making ceramic pottery.


Justin Aliozor-Anigbo, Undergraduate Student Researcher (August 2022 – Present): I am an OSU undergraduate who is currently majoring in Neuroscience with the intent to graduate in 2024. In the lab initially, I worked to help Matthew with his seasonal diapause project on Culex pipiens and then transitioned into doing research on Culex pipiens host-seeking behavior with the intent to publish and write a thesis. After graduation, I intend to take a gap year to work in the clinical field and research. I enjoy weightlifting, basketball, watching sports, and eating whatever Dr. Meuti bakes. 


Maria Fiorta, Post-Baccalaureate Research Assistant (August 2022 – Present): I earned my B.S. in biology from the Ohio State University in May 2023. I study how light pollution from urbanization impacts the molecular regulation of diapause in Culex pipiens. I work with Lydia Fyie on this project as well as Matthew Wolkoff on his transgenic Cx. pipiens seasonal biology project. Currently, I am applying for graduate programs to study entomology. Outside the lab, I enjoy hiking, kayaking, SCUBA diving, and aquarium keeping.


Hanna Paskvan, Undergraduate Student Researcher (July 2023 – Present): I am currently majoring in Natural Resource Management with an interest in Parks and Recreation here at OSU. After I receive my undergraduate, I plan to go for a master’s or PhD in wildlife conservation. I also have a bachelor’s degree in computer animation where my focus was 3D character modeling and design.  I am passionate about wildlife conservation and would like to combine my love for animation with wildlife conservation to help educate the public on the importance of wildlife and the environment. In my spare time, I like to bake, read, play video games, sculpt, draw, and hike/camp with my two dogs Benjen and Leia and partner Wyatt. Currently, I am helping Matthew with his research with the species Culex pipiens in the Meuti lab.


Chloe Chiu, Master’s Student (August 2023 – Present): I graduated from the University of California Riverside (UCR) with a B.S. in Cell, Molecular, Developmental Biology (CMDB) where I was part of Dr. Richard Redak’s lab studying the Glassy winged sharpshooter cuticular proteins involved with bacterial transmission and genetic editing as IPM. I joined the Meuti lab in the fall of 2023 to study how photoperiod may influence male mosquito ejaculate composition and how this affects post-copulatory modification of their partners. Outside of mosquito care, I enjoy reading historical books and baking.


Mizuki Yoshida, Post-Doctoral Scholar (October 2023 – Present): I graduated from the Department of Science in Osaka City University, Japan, with a degree of Doctor of Science. I am interested in how organisms survive in severe environments, such as Antarctica, and I have studied stress tolerance and mechanisms to make seasonality in the Antarctic midge Belgica antarctica during my Ph.D. period. In the Meuti lab, I study diapause in Culex pipiens. I am really excited to use my experience when I was a Ph.D. student and obtain new techniques in this lab! When she is not in the lab, she enjoys listening to music, playing video games, and watching wild birds.
