USRA Welcomes Two New Scientists!
Dr. Jessica Scott commenced her work as a USRA scientist at the beginning of December. Dr. Scott received her BSc from the University of Alberta (2003), her MSc from the University of British Columbia (2005), and completed her PhD in Cardiovascular Physiology at the University of British Columbia in June 2009. For her dissertation, Jess studied the effects of exercise on Jessica Scott, PhD cardiovascular function in elite athletes and heart transplant recipients and examined the consequences of exercise on orthostatic tolerance. She now serves as a post-doctoral fellow in the Exercise Physiology Laboratory at the NASA Dr. Mangala now serves in the Radiation Biology Lab at Johnson Space Center under the guidance of Dr. JSC under the direction of Dr. Honglu Wu. Her office is Lori Ploutz-Snyder. Her office is located in Buildlocated in Building 37, Room 119A. ing 261, Room 115. Dr. Lingegowda Mangala joined USRA in mid-November. Dr. Mangala received her Ph.D. from the Central Food Technological Research Institute (CFTRI) in India in 1998. After continuing her research career as a postdoctoral fellow at the Swedish University of Lingegowda Mangala, PhD Agricultural Sciences in Sweden and the National Food Research Institute in Japan (19992003), she joined the M.D. Anderson Cancer Center (MDACC) in Houston, TX as a Research Investigator. During her stay at MDACC, she worked on novel siRNA based therapeutic approaches for breast and ovarian carcinoma. Please join us in welcoming both Dr. Mangala and Jess aboard!

SPOTLIGHT ON: Shaowen Hu, PhD!
Shaowen Hu, PhD, works in the Space Radiation Health Project under the leadership of Dr. Francis Cucinotta. At the 55th Annual Meeting of the Radiation Research Society in Savannah, GA, this year, Shaowen received the prestigious Fowler Award. The Fowler Award recognizes an outstanding young investigator for exceptional work in radiation oncology, medical physics, and/or radiobiology. Shaowen was recently interviewed for this Spotlight article. * Tell us briefly about yourself and your family. My wife Xiaoying, our son Yijun, and I came from Wuhan, a well known “hot furnace” in China as Houston is for the US. Our second son Caleb enjoys the summer of Houston like us as he chose to come out in June. Currently both brothers go to T. H. Rogers School. This is one of the most marvelous schools I have ever visited. Houston Chinese Church is another place that our family goes together frequently. * What are you presently working on at JSC? A part of my work here is to conduct modeling simulations to assess the acute radiation risks from space radiation. These include prodromal risks, hematopoietic modulations, significant skin great scientists such as Newton, Maxwell, and Mendel were very religiously convicted.

What’s Going On With … ?
Lealem Mulugeta’s Digital Astronaut computational model has entered the beta testing stage. He is working with the Digital Astronaut team to solidify the science plan and vision for the project, and is strategizing ways to engage the project in STEM education. Larry Kuznetz volunteered as a beta tester for the Digital Astronaut computer program and provided feedback. Larry Kuznetz, PhD Larry also organized a telecom with UH, Virginia Commonwealth and NASA for the purpose of establishing a multi-disciplinary team to submit an NSBRI grant proposal for incorporating wireless technology into the spacesuit bioadvisory algorithm (LEGACI). Hatem Nounu reviewed the FORTRAN code of BRYNTRN with UHCL professor Terry Feagin and rewrote Hatem N. Nounu, PhD inefficient code segments, which resulted in run time savings of 25%. Lori Ploutz-Snyder co-chaired a muscle/bone panel for the standing review panel meeting, at which 39 national experts convened to review the HRP research portfolio. Jean Sibonga, seeking to assess boneHatem Nounu, PhD microarchitecture for central skeletal sites for the SLSD Innovation Strategy, is preparing written descriptions of rationale, background and impact to the

space program. Jean met with Dr. J.D. Polk to discuss convening a panel of leading osteoporosis clinicians in the spring of 2010 to formulate a Bone Health Policy for longduration astronauts. Johnny Conkin was asked by Dr. Tom Newman to contribute a chapter to the 6th edition Johnny Conkin, PhD of Bennett & Elliot, The Physiology and Medicine of Diving. As the sole author he will summarize 30 years of research to prevent DCS in shuttle astronauts. Further, Johnny is co-authoring a paper about break in prebreathe with Dr. Andrew Pilmanis, drafted a paper entitled “Decompression sickness after air break in prebreathe described with survival model” with Drs. Pilmanis and Webb, and is coauthoring a chapter in the Biomedical Results of the Shuttle with Dr. Mike Gernhardt. Megumi Hada worked the NSRL09C experiment run at Brookhaven National Laboratory and discussed progress and future plans for the collaborative project “Rad Gene” space experiment with Dr. Katsunori Omori of JAXA. Myung Kim completed the analysis of environmental and mission parameters of the recent 10 ISS missions according to dosimetry reports for the periods from September 2006 to November 2008, as well as the re-

cent 7 STS missions for the periods from June 2007 to November 2008. Ianik Plante completed the simulation of the association of a Brownian particle (TFGβ) with a partially absorbing boundary in 1D (cell membrane with TGFβ receptors) with the possi- Ianik Plante, MD PhD bility of dissociation and a decay channel for the TGFβ and TGFβ receptor. The first paper about this project, “Calculations of distance distributions, probabilities of binding and initiation of signal transduction by ligands in a cell culture in 1D membrane simulations”, is also complete. Ianik has now started calculations for extension of the model in 1D (2 membranes), 2D and 3D. Rob Ploutz-Snyder has been regularly teaching the DSLS Professional Development Course entitled SMAR (Statistical Methods and Applications Review) with great success. The lunch time classes are attended by about 30 people on average who highly appreciate his dedication, knowledge and Rob Ploutz-Snyder, PhD teaching skills!
