Research Interest

My research goals converge around the evolution of sexual reproduction. During my doctoral program, I investigated mitochondrial inheritance, a mechanism that ensures that mitochondria are only inherited from one parent. In the case of humans, children inherit mitochondria from their mothers, as the race to the egg during fertilization takes an important toll on sperm cells that damages their mitochondria. When this maternal inheritance mechanism is perturbed, rare mitochondrial diseases ensue, ranging from ophthalmic manifestations to muscular dysfunction. I decided to investigate the mechanism of biased mitochondrial inheritance from a fungal perspective. These organisms can reproduce sexually but do not differentiate into separate biological sexes. Instead, fertilization happens between two morphologically identical cells. Why would mitochondria need to be segregated appropriately? This fundamental question drives my fascination with the process of sexual reproduction and, accordingly, led to a fresh perspective as I continued my scientific training.

For my postdoctoral training, I decided to explore sex from a completely different lens, this time focusing on the mechanisms that allow for clear differences between biological sexes. Specifically, my current line of investigation focuses on the emergence and maintenance of sex chromosome systems. I am currently using the nematode C. elegans to model how sex chromosomes shape sexual dimorphism at both the genetic and developmental levels. This organism adds an additional layer of complexity to this work, as it comprises a hermaphroditic system in which males are naturally rare. Understanding and further characterizing the regulatory mechanisms behind sex chromosome can shed light on the evolutionary history of sex, in addition to potentially impacting the reproductive sciences.

As a PhD-trained scientist, you have many career options. What interests you the most?

I am interested in opportunities in academia, specifically in leading my own research laboratory and teaching both undergraduate- and graduate-level courses. As I transition into an academic position, I am still struggling with deciding what sort of institution I would like to join. While I would love to start my own research laboratory at a research-intensive institution and fully commit to training the next generation of scientists, I am very passionate about teaching and curriculum design. For this reason, I am exploring primarily undergraduate institutions, which focus on the education of undergraduates in a liberal arts context. I find this particular approach to post-secondary education quite impactful, as the undergraduate experience can be much more well-rounded and students can make the best decisions regarding their career paths. Additionally, I am quite excited to design and implement a research program that caters exclusively to undergraduate researchers, as their time in my lab will most likely be limited. The constant turnover in my lab, however, will mean that multiple students can contribute to a bigger project that can lead to a collaborative publication.

As an undergraduate, financial and time constraints prevented me from doing research and exploring how a biology degree could be used. If I am honest, I might reconsider my own decision to attend graduate school if I could turn back time. I thought it was the only logical path since I was not interested in a medical career. Thus, I want to make sure my future students are better prepared to make life-changing decisions. I am very interested in developing a strong mentorship philosophy both in the classroom and at the research bench. This interest has also made me consider administrative roles within academia and even secondary education.

In addition to your research, how do you want to advance the scientific enterprise?

I have been a non-traditional student for as long as I can remember, juggling schoolwork and multiple jobs to afford my education. I am also an immigrant, so the logistics involved in transferring colleges internationally turned out to be much more complicated than I had thought. These obstacles only made pursuing a science degree even more intimidating. I was constantly told that I was not putting in the hours needed to graduate or to move on to graduate school. Nevertheless, I persisted and completed my degree with flying colors. I will admit that I had a rough time getting to where I am today because I did not have anyone I could relate to. For this reason, I want students to realize that their paths towards their degrees will constantly evolve and will be shaped according to their own personal circumstances. I want to be part of my students’ journeys and be a guiding light when obstacles emerge.

I am also constantly educating myself on alternative science careers so that I am better prepared to provide advice and ensure students feel supported. For instance, I have experience in the clinical field, having worked as a Laboratory Clinical Processor during my doctoral training program. Though I acquired this experience out of financial necessity, I have come to realize that I can tell my students about these career paths, emphasizing that they are much shorter and inexpensive than medical or graduate school. It is still unsettling to think that the majority of STEM students go through their undergraduate careers fixated on one or two career options, even though demand is elsewhere. I want to emphasize that pursuing a scientific career can look so different for any individual. Its impact in society, however, will be rewarding and necessary.

As a leader within the Genetics Society of America, what do you hope to accomplish?

As part of the ECLP, I am thrilled to exchange ideas about effective communication and leadership. Accordingly, I am determined in establishing strong ties with colleagues in fields different from mine. As scientists, we can recite protocols from memory and perform intricate procedures with our hands. However, explaining why we do it is a creature of a different stripe. Programs like the ECLP take us out of our comfort zones, away from the bench, and challenge us to find the right word or visual to help an audience understand complex scientific concepts. During my tenure, I am hoping to venture out and explore opportunities in writing for non-academic settings and make science empowering.
