Aaron Vose
Aaron loves to have a good time and loves his toys (lasers, computer hardware, circuits, chemistry gear, model rockets).  He tries to find things to occupy his insatiable and fickle mind, albeit with limited success.  Aaron thinks consciousness is the universe's way of observing itself and thinks humanity needs to spread throughout space in an attempt to keep this interesting phenomenon around forever.

Aaron Vose is an PhD student in computer science at the University of Tennessee in Knoxville.  He works as a research assistant primarily for Dr. Igor Jouline, but will, on rare occasion, help Sergey Gavrilets. His duties include: implementation of simulations and data flows; management of distributed computation; data collection and analysis; computer system administration, purchase, and repair; as well as many other responsibilities.  He has worked closely with Sergey Gavrilets on a number of projects on topics from the evolution of human inteligence to speciation via adaptive radiation, many of which have resulted in publications.

Carrie Eaton
Carrie Diaz Eaton was born and raised New England.  She went to high school at Canton High in Massachusetts (go math team) and has always been a nerd.  College took her to the University of Maine where she pursued her love of math and zoology.  These days she enjoys family time, rooting for the Patriots football home team, sharing her love of teaching, and working towards that elusive PhD in Math!

Carrie is currently both a graduate teaching assistant in the math department and a research assistant in for Dr. Gavrilets through the Ecology and Evolutionary Biology department.  She developed a mathematics teaching program for graduate teaching assistants and currently teaches seminars in the fall and spring for this program.  As a research assistant, she has been interested in modeling evolutionary ecology - looking at how community interactions affect genetic evolution, primarily from a traditional population genetics point of view.  Prior work has included computational neuroscience and applied topology.

Ivan Juric
Ivan Juric was born in Zagreb, Croatia, Europe. In high school he met biology teacher who maintained several fruit fly stocks and let him play with them. During that time he became interested in genetics and evolution. Important to mention is that this high school had very strong program in Mathematics and computer science, so learning how to code was inevitable. School was also full of computer and math geeks who influenced Ivan's way of thinking; he was fascinated by different applications of a KISS principle in every day's life (for example in shopping).  After high school, Ivan studied molecular biology at the Division of Biology, Faculty of Science, University of Zagreb, where no one worked with fruit flies, but some guys in student organization liked to run in the fields and catch spiders. So he got introduced to field of ecology. Although working outdoors was interesting, for Ivan playing with computers is much more entertaining than playing with animals or sodium dodecyl sulfate polyacrylamide gel electrophoresis, which is something most of his friends (including mom and dad) still can't understand. During junior year Ivan finally combined interesting question with appropriate methods, which resulted in studying some properties of system where adaptations happens from standing variation by individual-based numerical simulations.  Currently Ivan is playing in the group of Sergey Gavrilets. He is interested in studying adaptation from standing variation, and also in using coalescent theory to answer various questions we can start asking now when there is huge amount of DNA sequences available.

Mauricio Gonzalez Forero
Once Mauricio was seduced by science, he never could escape from it. He finds it tremendously interesting and thinks it's a shame that he can only deal with a very limited part.  In addition to science, he enjoys playing the drums. Actually, he used to play in a progressive-rock band in Colombia called Jaén Kief.  He loves listening to Beethoven and Dream Theater and sometimes, when inspired, to practice his rather funny German.

Mauricio is interested in developing a mathematical basis for foundational problems in evolutionary biology such as the species problem and the notion of fitness. He is a masters student at Sergey's lab.

Edgar Duenez-Guzman
Edgar was born in Guadalajara, Jalisco, Mexico on 1981. Grew up in a house merely 300ft from the "Estadio Jalisco", at the time the second largest soccer stadium in Mexico, but for some reason refused to be a soccer die hard.  Resilient to most attempts of his uncle Ernesto to interest him on sports, young Edgar was exposed to the other passion his uncle had: Sience. At the age of 5, Edgar had already decided he wanted to be an Astronomer. Astronomy, however, was not to be Edgar's profession, as coming years would show.

It was when Edgar turned 6 that his family acquired its first personal computer. While the computer was intended for the eldest brother, Eduardo, it quickly became the source of immense curiosity for young Edgar. By the time the family acquired the now discontinued Commodore 64C, Edgar had already started writing his own programs. He spent most of middle-school programming in Logo and Basic.  By high-school, Edgar had regular access to a IBM compatible PC, and became interested in compiled programs, starting with Q-Basic and even a little of C. Edgar decided, however, that if he was to be a Computer Scientist at some time, then he would need to first become a real scientist and then attempt to learn serious computing. He did so by studying Mathematics as his undergrad.

During college, he became fully acquainted with C/C++ and Java, which to date are his favorite programming languages. After that, he made plans to study a Ph. D. in CS. The rest of the story unfolds in Knoxville, TN, USA.

Aysegul Birand
Aysegul spent a few years chasing birds in the rainforests of India. Her exposure to the tropics after spending years in a temperate ecosystem left her mesmerized with species diversity; hence her quest to find out the mechanisms leading to speciation. Unfortunately, she doesn't get to do field work anymore, rather she is playing with math and trying to learn C.

Aysegul completed her Bachelor's and Master's degree in biology at Middle East Technical University, Ankara, Turkey. She joined Nature Conservation Foundation's Centre for Ecological Research & Conservation, India for about two years as a research affiliate before she joined Ph.D. Program at the Department of Biology, New Mexico State University. Her dissertation focused on the theory of speciation, and she continues to struggle through the same topic.

Suzanne Sadedin
Suzanne's hobbies include nature photography, poetry, travel and messing around with artificial life.  She enjoys hiking in the Smoky Mountains and hopes one day to finish writing a novel.

Suzanne completed bachelor's degrees in Zoology and Psychology at the University of Melbourne before moving to Monash University for her doctoral work on computer simulations of speciation. She came to UTK as post-doctoral associate after two years as a research fellow at Monash. Her work during this time included investigations of cultural evolution, social networks, digital ecosystems, landscape genetics and the evolution of complexity, in addition to coauthoring a book and two review articles on self-organization and ecological complexity. Her current research focuses on the evolution of diversity at multiple scales, including ecotype formation, hybridization, speciation, and cultural evolution.

Arbiter Cluster


The Arbiter is a cluster of around 128 nodes, spread throughout the University of Tennessee in Knoxville, primarily in the Dept. of Computer Science and the Dept. of Ecology and Evolutionary Biology.  It is managed through a web interface written in PHP.  For details on requirements for an account, please contant Aaron Vose.  Also, the nodes run an Arbiter client, much like the SETI@home and Folding@home projects.  If you have a computer running Linux and would like to donate your spare cycles to our research, please let Aaron know, and he can get you connected with an Arbiter client.

(MPICH) AV Cluster


In addition to the Arbiter, a new resource is now available to the lab: a 6-node 24-core cluster utilizing AMD's 2.3GHz quad-core Phenom 9600 processor.  The cluster uses full-duplex gigabit ethernet for the node interconnect.  Each node offers 54GB of home area on local disk and 2GB of DDR2 800 memory.  A 54GB NFS share is also available.  The cluster currently supports MPICH 1.2.7 and has the ability to operate as a pool of arbiter clients as well.  For more details on this computing resource, please contact Aaron Vose.
