Abstract
African elephants (Loxodonta africana) are a highly social species that typically live in large, matrilineal family groups called herds which contain a linear dominance hierarchy between the adult females. Management plans for African elephants in human care try to replicate their natural social structures by creating small herds of females but these individuals are typically unrelated except in the case of mothers and their offspring. Despite low genetic relatedness, these females still create their own dominance hierarchies within the herds. Although elephants in human care have all of their needs provided for, dominance within herds can lead to preferential access to high-value resources such as food, water, and shade structures.
The purpose of this case study was to observe how the two female African elephants at Zoo Atlanta, Tara and Kelly, interacted with each other in terms of their usage of their current exhibit space. An incident occurred during data collection that led to a week-long separation of the elephants and the results of this study were then separated into two data sets. Anecdotal evidence of Kelly being the dominant individual was confirmed by Kelly initiating all 110 observed social interactions. After the incident there was a higher frequency of social interactions between the two elephants per hour. The amount of neutral and highly agonistic behaviors rose as well. It appears Kelly was re-establishing her dominance over Tara after their lengthy separation.
Both elephants had non-random patterns of exhibit spatial use when they were together and when they were alone in the exhibit, as well as before and after the incident. Before the incident, Kelly dominated use of the two areas that had direct access to the indoor barn when both females were in the exhibit together while Tara used the remaining two areas more often. These elephants have a complex social history, which includes Kelly dominating use of the barn and resources after a change to their social structure. As the dominant individual, Kelly had preferential access to this high-value area. Kelly continued to prefer staying in the areas closest to the barn when separated from Tara. The exhibit spatial use pattern displayed by Tara when separated from Kelly was different from her pattern when they were together because she used the area closest to the barn instead of the two furthest from the barn. The patterns after the incident were similar to those from the before results except Tara used the furthest area from the barn with a higher frequency when alone in the exhibit in addition to the closest. This change may have been caused by Tara’s restricted mobility after the incident.
Before the incident, all social interactions between the elephants and those that were agonistic in nature occurred randomly throughout the outside portion of the exhibit despite both elephants having specific patterns in how they used the exhibit. After the incident there was a non-random pattern in the location of all social interactions. More occurred in the area closest to the barn than would be randomly expected, which matches Kelly’s dominating use of that area. Although the occurrence of agonistic behaviors by area changed after the incident, the pattern was still random.

Abstract:
To quantitatively understand the cell behavior in molecular level, scientists have developed technologies including high throughput sequencing and flow cytometry. High throughput sequencing can obtain the entire genome sequence and measure expression of large number of genes. Flow cytometry can measure multiple parameters of large number of cells. Both technologies generate large amount of data in high dimension. Therefore, efficient methods to analyze and interpret the data become in demand. In my thesis, I focus on developing computational methods that deliver intuitive and interpretable visualization of biological data. The first chapter describes a software named Cluster-to-Gate (C2G) that can visualize existing clustering results of flow/mass cytometry data in the format of 2D gating hierarchy. Though C2G presents a way to visualize and interpret clustering results, the visualization is still data-driven and no human-knowledge is incorporated. To overcome the limitation of C2G, the second chapter describes a framework that can learn gating approach from existing publications to build a knowledge-graph. This knowledge-graph can automatically suggest order of marker usage and gating hierarchy for new data set, which can be used to gate cell populations. The obtained cell populations are immediately matched to known cell types in the knowledge-graph, which makes them interpretable. The third chapter describe a novel algorithm (GLaMST) to reconstruct lineage tree of B cell receptor gene from high throughput sequencing data. This algorithm outperforms state-of-art in both accuracy and speed.

Atlanta 500 Women Scientists is hosting a film screening of the award-winning documentary film "My Love Affair with the Brain: The Life & Science of Dr. Marian Diamond" (View the trailer here).

Part biography, part scientific adventure story, and part inspirational tale, this film details a story of a female neuroscientist who lived joyously at the forefront of scientific exploration and education, finding and sharing fact-based good news about the brain. 

The screening will be followed by a discussion featuring two local faculty in neuroscience, Marise Parent (Professor & Associate Director of the Neuroscience Institute at Georgia State University) and Audrey Duarte (Associate Professor in Psychology at Georgia Institute of Technology). They will discuss Dr. Diamond's impact on the field, as well as the science of learning, memory, and neuroplasticity. 

This screening is a fundraiser for our 501(c)3 nonprofit organization, 500 Women Scientists. They suggest a donation of $10-15, which will directly benefit outreach events hosted by the Atlanta 500WS pod and will help make science open, inclusive and accessible. All donations are tax deductible.

Register via Eventbrite, or RSVP through Facebook.

More about the film:

"My Love Affair with the Brain" is an award-winning PBS documentary that brings the viewer right into the heart of science and into a deeper understanding of your own brain.  Critically acclaimed, extensively tested for educational use from 5th grade thru Nobel Prize winners, this film is an intimate and inspirational portrait of one of the founders of modern neuroscience. 

Prepare to be smitten. Experience for yourself why Dr. Marian Diamond described her 60-year career researching the human brain as “pure joy.”

It is no exaggeration to say that Dr. Diamond changed science and society in dramatic ways over the course of her career. Her groundbreaking work is all the more remarkable as it began when so few women entered science at all. Shouted at from the back of the conference hall by noteworthy male academics as she presented her research, and disparaged in the scientific journals of a more conservative era, Dr. Diamond simply did the work and followed where her curiosity led her, bringing about a worldwide paradigm shift or two in the process. As she points out, in order to get to the answers that matter, you have to start by asking the right questions.

Part biography, part scientific adventure story, part inspirational tale, this is a story of a worthy role model, a woman who has lived joyously at the forefront of scientific exploration and education, finding and sharing fact-based good news about the brain.

Abstract:
Expression QTL (eQTL) detection has emerged as an important tool for unravelling the relationship between genetic risk factors and disease or clinical phenotypes. Most studies focus on analyses predicated on the assumption that only a single causal variant explains the association signal in each interval.  This greatly simplifies the statistical modeling, but is liable to biases in scenarios where multiple linked causal-variants are responsible. Here in this thesis, my primary goal was to address the prevalence of secondary cis-eQTL signals regulating peripheral blood gene expression locally, utilizing two large human cohort studies, each greater than 2,500 samples with accompanying whole genome genotypes.  The CAGE dataset is a compendium of Illumina microarray studies, and the Framingham Heart Study (FHS) is a two-generation Affymetrix dataset. I firstly describe performing simulation to reveal the potential interference of causal variants in LD regions. I then also describe a Bayesian co-localization analysis of the extent of sharing of cis-eQTL detected in both studies as well as with the BIOS RNA-seq dataset. Stepwise conditional modeling demonstrates that multiple eQTL signals are present for ~40% of over 3,500 eGenes in both microarray datasets, and that the number of loci with additional signals reduces by approximately two-thirds with each conditioning step. Although fewer than 20% of the peak signals across platforms fine-map to the same credible interval, the co-localization analysis finds that as many as 50%~60% of the primary eQTL are actually shared. Subsequently, co-localization of eQTL signals with GWAS hits detected 1,349 genes whose expression in peripheral blood is associated with 591 human phenotype traits or diseases, including enrichment for genes with regulatory functions such as protein kinase activity and DNA binding.  Just one quarter of these co-localization signals are replicated, further highlighting the technological and methodological barriers to reconciliation of GWAS and eQTL signals. My results are provided as a web-based resource for visualization of multi-site regulation of gene expression and their association with human complex traits and disease states. In addition to the cis-eQTL study, as a member of the eQTLgen consortium, I also conduct trans-eQTL detection in multiple cohorts, including FHS, which contains related individuals, and performed cis-trans eQTL mediation analysis, which I will as a side project.  This thesis provides novel insights into the complexity of gene regulation and the low consistency of fine mapping across studies, and introduces new software, PolyQTL, for colocalization of genetic signals in structured populations.

Summary
Understanding the genomic basis and origin of phenotypic variation is one of the fundamental questions of biology. Evolutionary radiations characterized by a range of natural phenotypic variants between genetically closely related species are a great model to study the origin and genetic mechanisms underlying phenotypic diversity. I use one such model, cichlids from Lake Malawi to understand the basis of complex behavior evolution. Lake Malawi cichlids are broadly divided into rock dwelling and sand dwelling lineages based on the habitat they colonize in the lake. Within this split on the basis of habitat comes a wide range of behavioral differences that define rock dweller and sand dweller cichlids. Within the sand dweller lineage, males build species specific bowers to attract females in seasonal leks. Whole genomes from 28 different cichlid species from Lake Malawi were used to show that:

(a) Most of the variation segregating rock dwelling cichlids from sand dwelling cichlids is in functional regions in the genome, associated with genes and pathways related to early brain development and adult behavior and

(b) Bower building behavior has repeatedly evolved via with polygenic selection on ancient and new genetic variants associated with genes and pathways involved in neural activity.
