Welcome to the2016 Astrobiology Graduate Conference

On behalf of the entire AbGradCon 2016 Organizing Committee, we would like to extend

a heartfelt welcome to all participants in the 2016 Astrobiology Graduate Conference at

the University of Colorado Boulder. AbGradCon is a unique and exciting opportunity - a

meeting organized by and for early-career researchers in all fields of astrobiology. This year’s

conference features contributions from more than 80 participants in an incredible diversity

of fields: astronomy, chemistry, biology, biochemistry, geology, planetary science, education,

mathematics, information theory, and engineering. We’ve come together in Boulder, Col-

orado, nestled in the foothills of the Rocky Mountains, to share our enthusiasm and our

passion for astrobiology.

AbGradCon is a chance for us to come together to share our research, collaborate, and net-

work, without the pressure of senior researchers. AbGradCon 2016 marks the twelfth year of

this conference–each time in a different place and organized by a different group of students,

but always with the original charter as a guide. These meetings have been wildly successful

both when connected to Astrobiology Science Conference (AbSciCon), and as stand-alone

conferences. Since it is organized and attended by only early-career researchers, AbGradCon

is an ideal venue for the next generation of career astrobiologists to form bonds, share ideas,

and discuss the issues that will shape the future of the field.

We hope that this, the 12th incarnation of AbGradCon, will prove as fruitful an experience

for all our participants as it has for us in the past. Serving on the Organizing Committee

has been a challenging, but extremely rewarding experience. We hope your experiences here

this year will motivate many of you to return in future years, both as participants, and as

members of the Organizing Committee. As with any endeavor which relies on a new group of

leaders with each iteration, there are bound to be bumps in the road. Please do not hesitate

to reach out to any member of the Organizing Committee should you have any questions –

we are committed to making this conference a resounding success!

Invited Guests

Irena Mamajanov is a Professor in the Earth-Life ScienceInstitute (ELSI) at the Tokyo Institute for Technology. Sheis a spectroscopist interested in systems chemistry, polymerscience and biomimetics. Dr. Mamajanov has been involvedin origin of life research since her PhD program at BrandeisUniversity where she worked under the tutelage of JudithHerzfeld on the structure elucidation of hydrogen cyanidepolymers via solid state NMR. Upon completion of her PhDprogram, Dr. Mamajanov took a postdoctoral position inNicholas Hud’s lab at the Georgia Institute for Technology,which led to a full research scientist position there. Her in-terests shifted towards condensation polymerizations, suchas the synthesis of nucleic acids, peptides and polysaccha-rides under thermodynamically unfavorable water solutionconditions.

In 2014, Dr. Mamajanov was awarded Simons Foundation Collaboration on the Origin ofLife fellowship. She then moved to Carnegie Institution of Washington to conduct her re-search on the origin of prebiotically plausible protein analogs. Dr. Mamajanov joined ELSIin January 2016. She has since been leading a research group studying so-called messy chem-istry. The group includes chemists, theoretical physicists, instrumental analysis experts andcomputer scientists. The goal of this effort is to understand the structure, behavior andemergent properties of complex prebiotically plausible reaction networks. Additionally, Dr.Mamajanov chairs the organizing committee of the upcoming ELSI Symposium that is totake place in January 2017.

Alexis Templeton is the Principal Investigator of theRock-Powered Life NASA Astrobiology Institute team anda professor of geomicrobiology in the Department of Geo-logical Sciences at the University of Colorado at Boulder,where she has been on the faculty since 2005. Dr. Temple-ton?s fields of expertise include microbe/mineral interac-tions, biomineralization, chemical imaging, spectroscopy,and isotope geochemistry. Dr. Templeton directs researchfocused on defining the pathways and products of abi-otic and microbial electron-transfer processes in laboratorysystems, and she is actively engaged in serpentinizationfield studies based in Oman, as well as sulfur biomineral-ization field studies on Ellesmere Island, Canada that have

relevance to Mars and Europa. The Templeton lab has previously conducted research onthermophilic metal-cycling organisms in the deep subsurface at Henderson Mine, Colorado,and on submarine bioalteration of oceanic crust at Loihi Seamount, Hawaii and Vailulu?uSeamount, American Samoa.

Dr. Templeton earned a B.A. and M.S. in Earth Sciences at Dartmouth College in the areaof isotope geochemistry, which led to technical position at Lawrence Berkeley National Lab-oratory applying isotope techniques to bioremediation efforts. She then pursued a PhD inEarth Sciences, specifically the new field of geomicrobiology, at Stanford University, followedby a NSF Postdoctoral position in Marine Biology at Scripps Institution of Oceanography.In her PhD and postdoc, Dr. Templeton developed expertise in synchrotron based x-rayspectroscopy, chemical dynamics in biofilms, and the cultivation of metal oxidizing organ-isms that inhabit rock-hosted ecosystems, which then shaped the research directions she haspursued in her current faculty position at CU Boulder.
