All colloquia are in Wege Auditorium at 1:10pm on the dates below (except where noted).
September 7, 2018 – Norm Bell, Safety talk for all students working in labs. This is mandatory!!
September 14, 2018 – “Strategies for designing and delivering a scientific presentation” (by Matt Carter, Assistant Professor of Biology)
It takes time, effort and skill to design and deliver an engaging scientific talk that audiences understand and remember. In this one-hour presentation, we will discuss three aspects of designing an outstanding scientific talk: (1) organizing complex scientific information into a clear narrative; (2) using PowerPoint or Keynote software to visually communicate scientific concepts; and (3) improving verbal and nonverbal delivery during a presentation. This seminar is open to anyone and is especially applicable to senior thesis students.

“The promise of human genetics in uncovering the biological mechanisms underlying neurodevelopmental disorders and mental illnesses”
In the past two decades, notable technological and methodological advances in human genetics has enabled the analysis of the genetic code of many tens of thousands of individuals, and for first time, a comprehensive look into the genetic factors underlying human traits and diseases. This has been particularly revealing in the study of mental illnesses, where our understanding of the genetic and environmental causes are still limited. Here, I will discuss the emergence of next-generation sequencing as a tool in identifying large-effect protein-coding variants that are associated with higher risk of mental illnesses, with a focus on schizophrenia. I will first review earlier results from the UK10K project, in which the analysis of over 5,000 case exomes revealed a schizophrenia risk gene and shared connections with broader neurodevelopmental disorders. I will then present preliminary results from the Schizophrenia Exome Sequencing Meta-analysis Consortium, a global collaborative effort to further accelerate genetic discoveries in schizophrenia through the analysis of over 75,000 individuals. These analyses are identifying genes and biological processes that underlie mental illnesses, and provide one avenue in acquiring clues on possible drug targets that may lead to more effective treatments.

“Stem Cell Signals in Cancer Heterogeneity and Therapy Resistance”
Our research focuses on the signals that control stem cell self-renewal and how these signals are hijacked in cancer. Using a series of genetic models, we have studied how classic developmental signaling pathways such as Wnt, Hedgehog and Notch play key roles in hematopoietic stem cell growth and regeneration and are dysregulated during leukemia development. In addition, using real-time imaging strategies we have found that hematopoietic stem cells have the capacity to undergo both symmetric and asymmetric division, and that shifts in the balance between these modes of division are subverted by oncogenes. Further, regulators of this process, including the cell fate determinant Musashi, are critical players in driving progression of solid and liquid cancers and could serve as targets for diagnostics and therapy. Ongoing work is focused on understanding the mechanisms that drive therapy resistance after drug delivery, as well as developing high resolution in vivo imaging approaches to map normal stem cell behavior and interactions within living animals, and to define how these change during cancer formation.
October 5, 12, 19, 2018 – Thesis Talks (two of these three dates, depending on Mountain Day)
November 2, 2018 – (BIOL Class of 1960 Scholar) Dan Bolnick ’96, University of Connecticut
February 8, 2019 – Sara Wasserman, Wellesley College
February 22, 2019 – (BIOL Class of 1960 Scholar Event) Alumni Reunion – The purpose of the reunion is to provide our students a window on the process of finding and gaining admission to graduate Ph.D or MD/Ph.D programs. The reunion has two parts. First, a panel discussion will be led by our visiting alumni who are now in Ph.D, MD/Ph.D or post-doctoral programs (in Wege @ 2pm). Second, the panel will be followed by a poster session where students can talk individually with the panelists about their current research and about other topics related to moving forward towards a career in basic or medical research (in TBL 211 @ 3pm).
March 1, 2019 – Patricia Brennan, Mt. Holyoke College
March 8, 2019 – Byron Weckworth, Panthera, Director Snow Leopard Program
“Conservation in practice: from academics to grass roots”
The guiding principles in conservation dictate the importance of preserving biodiversity, maintaining ecological complexity and upholding evolutionary potential, as well as identifying that biodiversity has intrinsic value and that untimely extinctions should be prevented. Conservationists play many roles across various fields within the basic sciences and resource management. Conservation in practice requires successfully navigating the feedback loop between the new ideas and approaches provided by science and the field experience and research needs of resource managers, and then implementing the results into management and policy directives. Yet, in some cases, successful conservation dispenses with the formalities of this exchange in favor of local, grass roots interventions. Drawing from my own professional experiences in wildlife research and conservation, we will review results from studies of phylogeography, population genetics and ecology, predator-prey dynamics and social surveys, and examine the success and failure of their application to endangered species listing efforts for the Alexander Archipelago wolf, management of threatened woodland caribou in western Canada, and human-snow leopard conflict in Qinghai, China.
