The Promise and Practice of Inclusive Education

Education holds the promise of preparing students to be engaged, thriving participants in a socially just democracy. For that ideal to occur, the structure and experience of the classroom must reflect both its constituents and consider the socially just imaginaries in which we would all like to inhabit. Using examples from the civil rights era's interrogation of our society, we will explore how an introductory biology course can help fulfill higher

"Insights from a Quarter Century of Work on the Ecology of Behavioral Syndromes"

Selfie Dr. Andy Sih | Sih Lab

Andy Sih’s laboratory works on the evolution of ecologically important behaviors (predator-prey, mating, and social behaviors) life history traits, and how these influence population and community ecological patterns,  Most projects examine freshwater organisms e.g., fish amphibian larvae, crayfish, insects and other freshwater invertebrates.  Current applied ecological interests include studying effects of pesticides on predator-prey interactions, and behavioral mechanisms underlying species invasions.

"Timekeeping in Latitudinal Avian Migrants: A Story from Buntings"

SelfieDr. Vinod Kumar | Kumar Lab

Abstract:
Cycles in biological systems are all-pervasive in nature. Birds, like any other species, express daily rhythms in activity/rest, hormone secretion, and several other rhythmic characteristics. Most bird species also show long-term cycles in feeding behavior, body fattening (in migrants), reproduction, molt, or migration. Both daily and seasonal behaviors are under the strict control of the endogenous clock mechanisms, but the role of the environment remains critical for optimal performance and ultimately survival. Synchrony with the environment is achieved through the interaction of clock components with external cues (e.g. photoperiod), and internal coordination among different rhythmic physiological correlates is achieved through neural and endocrine signaling. Thus, we are interested to learn about how birds achieve precision in timing their daily and seasonal activities in sync with the periodic environment. Our research effort mainly centers around the “Avian Circadian and Seasonal Systems: Study from Behavior to Molecules”. The working hypothesis has been that specialized cells localized in different tissues express genes involved in the clock circuitry, and different cell populations control the food intake, body fattening, reproductive axis, molt, and migration, in a way that each event can be timed and spaced with each other to optimize an ecological adaptation.

"Functional Screening Approaches to Identify Cellular Toxicity Mechanisms"

Bio
Chris Vulpe, MD, PhD. is a Professor at the University of Florida, Gainesville in the Center for Environmental
and Human Toxicology. Dr. Vulpe received his MD and PhD from the University of California, San Francisco.
Dr. Vulpe’s group uses systems level approaches in eukaryotes from yeast to people to identify the functional
components that respond to and modulate the consequences of environmental stressors. Most recently, his laboratory is utilizing genome wide and targeted CRISPR screens to understand the mechanisms of toxicity of environmental chemicals. Dr. Vulpe is an author or co-author on >175 papers in peer reviewed journals and books. His group uses functional, genomic, and genetic approaches to provide insight into mechanisms of toxicity in diverse model systems including human models such as human cell culture, organoids, and rodents, as well as ecologically relevant organisms such as Daphnia magna.

601 Seminar | "Long-distance Relationships in the Control of Gene Regulation During Development, Disease, and Evolution"

SelfieDr. Francois Spitz | Spitz Lab

Bio:
PhD from Université Paris 6 (France)
Group Leader at the European Molecular Biology Laboratory (2006-2015) (Heidelberg, Germany)
Head of Research Unit at the Institut Pasteur (2015-2019) (Paris, France)
Professor, The University of Chicago (2019-.)

Abstract:
The mechanisms that regulate the efficiency and specificity of interactions between distant genes and cis-regulatory elements such as enhancers play a central role in shaping the specific regulatory programs that control cell fate and identity. In particular, the (epi)genetic elements that organize the 3D folding of the genome in specific loops and domains have emerged as key determinants of this process. I will discuss our current views on how 3D genome architecture is organized, how it influences gene regulatory interactions and illustrate how alterations of the mechanisms and elements that organize genomes in 3D could contribute to genomic disorders and genome evolution.

"Phased, Secondary siRNAs in Plant Reproduction and Other Pathways"

SelfieDr. Blake Meyers | Meyers Lab

BIO: 
Blake Meyers is a Member & Principal Investigator at the Donald Danforth Plant Science Center in St.
Louis, and he is a Professor in the Division of Plant Science and Technology at the University of
Missouri - Columbia. He formerly held the Edward F. and Elizabeth Goodman Rosenberg
professorship at the University of Delaware, where his research group was from 2002 to 2015. He
was elected as a Fellow of the American Association for the Advancement of Science (AAAS) in 2012,
and a Fellow of the American Society of Plant Biologists (ASPB) in 2017, the same year he was
awarded the Charles Albert Shull Award by the ASPB for outstanding investigations in the field of
plant biology. He was elected to the US National Academy of Sciences in 2022. After serving on the
editorial board since 2008, Blake became the Editor-in-Chief of The Plant Cell in January 2020. Work
in his lab addresses the biological functions, biogenesis, genomic impact, and evolution of small
RNAs in diverse plant species, using combination of genomic and molecular genetics approaches,
with a focus on phased, secondary siRNAs (“phasiRNAs”).

He received his undergraduate degree in biology from the University of Chicago in 1992, and
working with Prof. Richard Michelmore at UC Davis, was awarded M.S. and Ph.D. degrees in genetics in 1995 and 1998, respectively. After that, he did a postdoc with Prof. Michele Morgante at DuPont Crop Genetics, working on maize genomics for 2 years before returning to Prof. Michelmore’s group at UC Davis in 2000 to do a 2nd postdoc on Arabidopsis disease resistance. In 2002, Blake started his
own research group at the University of Delaware. He was the chair of the Department of Plant & Soil Sciences at the University of Delaware from 2009 to 2015.

Abstract:
In plants, 21 or 22-nt miRNAs or siRNAs typically negatively regulate target genes through mRNA cleavage or translational inhibition. Heterochromatic or Pol IV are 24-nt and function to maintain heterochromatin and silence transposons. Phased “secondary” siRNAs (phasiRNAs) are generated from mRNAs targeted by a typically 22-nt “trigger” miRNA, and are produced as either 21- or 24-mers via distinct pathways. Our prior work in maize and rice demonstrated the temporal and spatial distribution of two sets of “reproductive phasiRNAs”, which are extraordinarily enriched in the male germline of the grasses. These two sets are the 21-nt (pre-meiotic) and 24-nt (meiotic) siRNAs. Both classes are produced from long, non-coding RNAs, generated by hundreds to thousands of loci, depending on the species. These phased siRNAs show striking similarity to mammalian piRNAs in terms of their abundance, distribution, distinctive staging, and timing of accumulation, but they have independent evolutionary origins. The functions for these small RNAs in plants remain poorly characterized. I will describe our recent work investigating the functions of plant phasiRNAs and their roles in modulating traits of agronomic importance in plants, including male fertility, as well as novel applications of phasiRNAs such as those generated from transplastomic plants.

Dr. Tishkoff studies genomic and phenotypic variation in ethnically diverse Africans. Her research combines field work, laboratory research, and computational methods to examine African population history and how genetic variation can affect a wide range of traits – for example, why humans have different susceptibility to disease, how they metabolize drugs, and how they adapt through evolution.

Education holds the promise of preparing students to be engaged, thriving participants in a socially just democracy. For that ideal to occur, the structure and experience of the classroom must reflect both its constituents and consider the socially just imaginaries in which we would all like to inhabit. Using examples from the civil rights era's interrogation of our society, we will explore how an introductory biology course can help fulfill higher
education's civic mission.
