Fritzie Brady, PhD

research Associate

Fritzie joined the Conrad lab as a Senior Research Associate in July 2022.  Her research background utilizes fish models to study the roles of hormones and the effects of environmental stressors including endocrine disrupting chemicals on growth, reproduction, and stress response.

Fritzie is excited to venture into biomedical research, and she is currently contributing to the technical aspects of several projects in the Conrad lab as well as in the management of the wet lab. She is looking forward to characterize the normal function of the testis, as well as the effects of environmental and genetic causes of testicular dysfunction in mammals. She is also interested in the roles of stress and immune responses in pathology. 

Fritzie completed her PhD in Bioresource Production Science (Aquaculture and Livestock Production- Fish Reproductive Physiology) in the laboratory of Prof. Takeshi Miura at Ehime University in Matsuyama, Japan. Her dissertation focused mainly on endocrine physiology, in which she studied the effects of arsenic and oxidative stress on spermatogenesis and the mechanism of their effects involving the antioxidant defense system in the testis using the Japanese eel (Anguilla japonica) as a model. The results of this research work provided insights into the molecular mechanisms of the tolerance of spermatogonia to oxidative stress.

She worked as a Research Specialist at the University of Hawaii in Honolulu where she led a research project in determining the long-term effects of early-life exposure to estrogenic endocrine disrupting chemicals on growth and reproductive physiology in tilapia. One of her major works also include characterizing the mechanisms associated with the endocrine control of growth and reproduction that may underlie sexual dimorphism using tilapia as a model.

Outside the lab, Fritzie loves photography, road trips, discovering new places, and fishing.

Ana Lima, PhD

Research Associate

Ana joined the Conrad lab as a post-doctoral fellow in August 2016.

One can say that Ana has always enjoyed a complex puzzle. Her passion for problem solving and learning has led her to explore the field of Genetics in many contexts.

She received her PhD at the University of Porto in 2016 and was co-advised by Don, thus spending time the Conrad Lab since 2012. During her doctoral work, Ana came across one of the major challenges of Human genetics: How to interpret the functional relevance of genetic variation in the context of disease? She has since been fascinated by the complexity of the mechanisms regulating expression of genes into a variety of functional proteins. Currently, Ana is interested in understanding the regulatory networks that control spermatogenesis progression, mainly focusing on post-transcriptional regulation, and how the disruption of these fine-tuned mechanisms may affect germ cell development and lead to male infertility. Her most recent challenge has been to put her pipettes down and integrate computational approaches in her research.

Tora Roberts, PhD

Affiliated Research Faculty

Tora is a Research Associate Professor in the Division of Reproductive & Developmental Sciences at ONPRC and is a close collaborator of the Conrad Lab. She is a placenta nerd! The placenta is a remarkable organ that supports the growth and development of the fetus while also growing itself. Regulation of function needs to be tightly controlled to ensure a healthy outcome for both mother and baby. During her studies and early career, Tora worked with human samples and since the start of 2009, she has been at the ONPRC utilizing pregnant nonhuman primate (NHP) models. She is a rare find in science, a researcher who has never used a rodent model!

Tora got involved in with the Conrad Lab in April 2022  as the Program Manager for the NHP dGTEx (developmental genotype tissue expression) consortium. Her experience with pregnant NHPs is an excellent fit in running this project which will build a large unique tissue and genomic data resource from both old and new world monkey species. Tora is especially excited about obtaining early gestation placenta samples which she will utilize to develop a 3-dimensional trophoblast organoid model system from the rhesus macaque.

Tora obtained her PhD in placental physiology from the University of Manchester, UK in 2004. Her research focused on the role of purinergic receptors in placental homeostasis and she gained a lot of experience in using primary cells as an in vitro model system. After obtaining her PhD, she moved to the University of Cincinnati, OH where she completed a 4-year postdoc from 2004 – 2008. During that time, she continued to investigate regulation of placental function, and expanded her interests to mechanistic studies of what goes wrong in compromised pregnancies.

Outside of the lab, Tora loves to bake! She also enjoys reading and swimming but much of her free time involves soccer – mostly cheering from the sidelines!  When she eventually retires her lab coat, she’d like to run a dog rescue.
