Title: Bats Aren’t Blind but Some Might Suck Your Blood
Abstract: Bats are the only mammals capable of powered flight and are found on every continent except Antarctica. There are over 1,400 species of bats, ranging in size from as big as your thumb to those with a wingspan of 6 ft. Not only is the evolution of powered flight unique, bats have developed other fascinating features such as echolocation, using torpor, carrying but rarely dying from diseases, and even evolving to feed on blood. This talk will provide some background about bat evolution, discuss bat facts and myths, and a little conversation about how we study bats. “Fly in” out of curiosity, “hang around” for the photos of adorable sky puppies

Title: What Are The Odds? A Brief Tour of Counterintuitive Results in Probability
Abstract: The field of probability is rich with questions that are easy to state but have surprising results. One well-known example of this is the so-called "Monty Hall Problem," which famously frustrated even the famed mathematician Paul Erdös. In this talk, we will assemble a collection of questions in probability theory whose answers tend not to match most people's first guess. This talk is intended to be accessible to anyone at any level of mathematics, yet (hopefully) still interesting to those who are well-versed in probability theory.

Title: You Are What You Eat: How Nutrient Availability and Organic Matter Source Dictate Genomic Potential and Viral Activity in Coastal Anoxic Sediment
Abstract: Microbes make up the majority of the biomass in sediment, where they play a role in cycling organic carbon and regulate the fluctuation of organic matter. In anoxic sediment, the relationships between geochemical gradients, genomic potential, and virus-host interactions remain understudied and poorly understood. I will present the results of our study of stratified sediments from anoxic sinkhole (Blackwood Sinkhole, Bahamas), where we analyzed the pore water chemistry analysis (nutrients, carbon, nitrogen), microbial community composition (16S rRNA gene and metagenomics), and virus-host interactions. Through the characterization of the relationships of microbes between each other and with their environment, we aim to identify the role organic and inorganic matter availability plays in shaping viral and prokaryotic communities, as well as how microbial communities shape their environment.

Title: Growth in Groups: Using Algebra and Geometry to Study Symmetries
Abstract: The concept of symmetry is often viewed from an artistic perspective, but in mathematics, collections of symmetries are fundamentally important objects called groups. Familiar examples include the symmetries of geometric shapes such as squares or circles, but more exotic examples abound. In this talk, I will introduce some different kinds of groups and show how their properties are revealed by geometric visualizations of groups called Cayley graphs. This talk is intended to be accessible regardless of mathematical background.

Title: Crowdsourcing Recommendation System
Abstract: Crowdsourcing is an approach whereby employers call for workers online with different capabilities to process a task for monetary reward. With a vast amount of tasks posted every day, satisfying the workers, employers, and service providers who are the stake- holders of any crowdsourcing system is critical to its success. To achieve this, the system should address three objectives: (1) match the worker with suitable tasks that fit the worker’s interests and skills and raise the worker’s rewards and rating, (2) give the employer more acceptable solutions with lower cost and time and raise the employer’s rating, and (3) raise the rate of accepted tasks, which will raise the aggregated commissions to the service provider and improve the average rating of the registered users (employers and workers) accordingly. For these objectives, we present a mechanism design that is capable of reaching holistic satisfaction using a multi-objective recommendation system. In contrast, all previous crowdsourcing recommendation systems are designed to address one stakeholder who could be either the worker or the employer. Moreover, our unique contribution is to consider each stakeholder to be self serving. Considering selfish behavior from every stakeholder, we provide a more qualified recommendation for each stakeholder. We also discuss related problems.

Title: New Twists on a Classic: The Cope Rearrangement
Abstract: Topological and functional complexity are key to designing bioactive molecules. Synthesizing targets concisely via simple chemical means from abundant starting materials is paramount. Thus, our goal is to contribute new methods, strategies, and philosophy for simultaneously addressing simplicity and complexity in chemical synthesis. We are drawn to 1,5-dienes and 1,5-enynes derived from alkylidene pronucleophiles and allylic or propargylic electrophiles. Upon Cope rearrangement, a stereochemically complex building block bearing useful functional groups for interconversion is obtained. Thus, we aim to develop this sequence as a “toolbox” strategy for preparing topologically and functionally complex pharmaceutical leads of general value to synthetic- and medicinal chemists. We also aim to validate our strategies via select applications in complex molecule synthesis. Challenging the utility of this strategy are often kinetically and thermodynamically unfavorable Cope rearrangements and a dearth of methods for achieving this sequence enantioselectively. Thus, success for this project requires addressing these fundamental challenges through the development of chemical methods and applying the newfound understanding in the synthesis of relevant targets.

Title: Metal Pollution in Aquatic Environments
Abstract: Metal contaminants have been a growing problem in aquatic systems due to their many uses in modern society, especially in the development of state-of-the-art technological devices and advancements. Anthropogenic land-based sources of metal contamination include industrial discharges into streams or rivers, agricultural runoff, sewage treatment discharge, domestic stormwater runoff, and leachates from metal-based antifouling paints. In excess, metals can accumulate in both plant and animal tissues, cause toxicity, and move through the food chain potentially impacting humans through consumption of aquatic species. Research pertaining to the chemical and biological effects of metals being released into the environment is of critical research importance. This talk will discuss metal pollution in the St. Johns River and metal accumulation and effects in important keystone species such as sharks and dolphin.
Bio: Dr. Bielmyer-Fraser received her B.S. from University of North Florida and M.S. and Ph.D. in Environmental Toxicology from Clemson University. Dr. Bielmyer-Fraser worked as a Post-Doctoral Fellow in the Marine Biology and Fisheries Department at the University of Miami and then in 2008 became a faculty member in the Biology department at Valdosta State University. Dr. Bielmyer-Fraser joined the faculty in the Chemistry department at Jacksonville University in 2016. Dr. Bielmyer-Fraser has been pursuing research in the field of Environmental Toxicology with a focus on aquatic systems for 20 years.
