Wen-Juan Ma, Ph.D. and postdoctoral research associate at Amherst College, will present "Evolution of Homomorphic Sex Chromosomes, Sex-Biased Gene Expression in the Common Frog."
"My research focuses on the fields of evolution and genomics of sex chromosomes and mating-type chromosomes, sex determination, as well as evolution of asexuality (especially induced by the bacteria Wolbachia). To understand the evolution and genomics of sex chromosomes and sex determination, I have used a broad range of non-model organisms, including invertebrate haplodiploid parasitic wasps, vertebrate amphibians, angiosperm plants and parasitic plant anther smut fungi, using various approaches in combination of fieldwork, experimental crosses, common garden experiment, molecular genetics and comparative genomics. Previously, my work on genomics of homomorphic sex chromosomes in the common frogs was investigating of evolutionary signatures of early stage of sex chromosome evolution, such as transcriptional degeneration, feminization of X chromosomes, dynamics of sex-biased gene expression throughout development and among adult tissues. The results revealed that sex-biased gene expressions were not enriched in sex chromosomes, no transcriptional degeneration occurred and no Faster-X (sex chromosome) evolution evolved, suggesting the canonical model of sexual antagonistic selection might not play a critical role at least in amphibian sex chromosome evolution. Currently, I am using comparative genomics approach to investigate temporal degeneration of non-recombining mating-type chromosomes in a series of anther smut Microbotryum fungi species."
Startup studio Loeb.NYC is continuing its commitment to entrepreneurial internships in NYC. Michael Loeb ’77, P’21 (serial entrepreneur, founder of Loeb Enterprises/Loeb.NYC and co-founder of Priceline), along with Nicole Williams (founder of portfolio company 'WORKS', 3-time bestselling author and regular talk show guest), have collaborated to bring you the Loeb.NYC Summer Internship Program for the third year in a row.
Loeb.NYC's 10-week, paid internship program provides training and first-hand NYC startup experience to approximately forty bright undergraduate students with an enthusiasm for business and innovation. This is a one-of-a-kind opportunity for students to learn about entrepreneurship and make a difference at a startup. Attend this information session to learn more about the internship program and how to successfully apply to be part of the Summer 2019 cohort!
The internship kicks off in early June, when interns join Michael and Nicole at Michael’s Southampton house (if you’ve seen Billions on Showtime, it’s that Hampton house), where they are immersed in a one-day training program. The next day, the CEOs of the startup companies selected for the summer program pitch their businesses and summer projects to the interns. After individual meetings between the startups and the students, each intern is matched with a company that closely fits their skills and interests. To ensure this program is a success for interns and companies, company CEOs create defined assignments with meaningful work and oversight.
The internship program is supportive and comprehensive. Each intern receives a subject matter introduction to business and entrepreneurship, obtains support throughout the 10 weeks and is provided with resources enabling them to succeed. Every week, interns visit the Loeb.NYC home office for our version of an evening 'Ted Talk' featuring world class entrepreneurs discussing, well, just about anything they want to. In addition, interns participate in a weekly roundtable where progress is reviewed and concerns are discussed.
