Dr. Dennis MatthewsWe're continuing to progress forward with our plans for Biophotonics Week this September 2010 to be held in Quebec City, Canada.  Please visit our website,, for frequent updates.  During the end of February we have been preparing for Dr. Arden L. Bement Jr.'s (the Director of the National Science Foundation) visit to the University of California, Davis on Friday, March 5, 2010.  As part of his visit he will stop by our Center for Biophotonics for a short presentation and tour of our research laboratories.  The Board of the Tahoe Institute for Rural Health Research (TIRHR) will also be visiting UC Davis in early March to discuss rural healthcare needs with the UC Davis Health System as well as spend time at CBST.

CBST Research Highlights
Meet the Researcher - Dr. Matthew Coleman
Dr. Matthew ColemanDr. Matthew Coleman is currently an Associate Adjunct Professor at the University of California, Davis in the Department of Radiation Oncology and a member of the NIH Cancer Center within the medical center.  Dr. Coleman also holds a scientific appointment as a Senior Scientist at the Lawrence Livermore National Laboratory in Livermore, California

Dr. Coleman's research focuses on understanding the processes involved in genome instability following genotoxic stresses such as ionizing radiation. Dr. Coleman's research also uses novel approaches in nanotechnology using nanolipoproteins to help characterize biological components involved in cell signaling.
Dr. Coleman's training is in molecular biology where he received his B.A. from the University of Massachusetts, and his Ph.D. in biophysical studies of membrane proteins from Boston University.  He has authored over 60 publications in peer-reviewed journals, published proceedings and book chapters covering a diverse breadth of molecular biology and biochemistry. Dr. Coleman has three patents and 6 patents pending related to biomarker discovery and biotechnology.  For his work in the area of nanolipoproteins -membrane protein complexes Dr. Coleman received a Nanotechnology 50 award for co-development of his innovative approach to produce and solubilize membrane proteins using nanoparticles.
Research projects in Dr. Coleman's laboratory include radiation biology and applications to point-of-care detection using biosensors:
- Biodosimetry
- Human genetic variation
- Cancer detection
- Adaptive responses
- Biological responses to radiotherapy
His research work has been supported by several agencies including DOE, NIH and LLNL.

CBST Education Highlights
CBST represented well at the Sacramento Regional Science & Engineering Fair - March 2010
2010 Sacramento Regional Science & Engineering FairIn the last weekend of March hundreds of 6th- 12th grade students representing nine Northern California counties will enter the main building of Rosemont High School for the Sacramento Regional Science and Engineering Fair (SRSEF).  Among the group will be ten Sacramento high school students involved in CBST's Cancer Science and Biophotonics Research Academy.  The science fair will be a chance for them to showcase their research in topics raging from Breast and Prostate cancer to Vitamin B17 Toxicology effects on Black worms.

The high school students are part of the Education program at CBST that links local high school students with labs, guest speakers and curriculum focusing on cancer research. The students participate for a full school year followed with a summer cancer research experience.

The Sacramento Regional Science and Engineering Fair will also offer the students an opportunity to share their experiences with CBST, practice their presentation skills, and win scholarships and prizes. The event is free to students and the public on March 27th (free parking also)

If you are interested in attending or volunteering please contact the fair website at 
CC Winter Internship Program
In January 2010 (4th-16th), twenty-four students from thirteen community colleges in Northern California participated in the third cycle of the Winter Research Program for Community College Students at CBST (program known as 'CCWinter').  This year the program was co-facilitated by Drs. Corbacho and Gurkoff  and co-funded by CBST (NSF funds) and the UC Davis College of Biological Sciences (HHMI funds).  Twenty-two of the students plan to transfer to a four-year university in 2010, of which sixteen plan to transfer to UCD as their first choice.  The majority of the participants  (83%) are working students, with an average of 18 work-hours per week.

2010 CCWinter InternshipParticipating Community Colleges with students noted in parentheses: American River College (6), Cañada College (1), Contra Costa College (1), Consumnes River College (3), Hartnell College (1), Mendocino College (1), Merced Community College (1), Mission College (1), Napa Valley College (1), Sacramento City College (2), Skyline College (1), Solano Community College (2), Yuba College (2).

Interview with a future researcher - ET-CURE program participant from CBST
Laura RamirezName: Laura Ramirez
Current University/School: Undergraduate at CSU Sacramento
Lab assignment: Dr. Kit Lam

What does the ETCURE program offer you?
  The ET-CURE (Engineering Technologies Continuing Umbrella Research Experiences) program is my opportunity to do research directly related to cancer. The experience developed from this program will strengthen my research ability and continue my preparation to contribute to the scientific community in the search for a cure for cancer.
What sparked your interest in science and specifically science research?  As a child I was always intrigued with science.  My parents enrolled me in Saturday classes and after school programs that almost always involved science.  I remember building bottle rockets, volcanoes that erupted red slough, solar cars and ovens. At the end of those projects I was always left with questions about the forces related to those reactions.
What are you working on now with your ET-CURE research?  I am currently working on imaging bacteriophage on PVA-PEG beads with a transmission electron microscope and scanning electron microscope in order to visualize the orientation of binding between both.  It is essential to do this in order to verify that in fact the protein expressed on the head of the phage is actually what is binding to the ligand on the bead. 
If you where invited to talk to your grade school how would you encourage them to pursue science/research?  I would present them with as much statistical information showing the health disparities that exist with minorities and cancer.  I would also present them with the data shown for underrepresented students in the sciences.  I believe this would make a significant impact on them because the majority of the students at my Jr. High and High School are underrepresented students. 
CBST Knowledge Transfer Highlights
SARTA 7th Tech Index Celebration - February 17th, 2010
Members of the CBST Knowledge Transfer team (Tod Stoltz, Gabriela Lee, and Amy L. Gryshuk) attended the 7th edition of SARTA's Tech Index Celebration held at the Hyatt Regency in Sacramento, whose purpose is to honor Sacramento's leading 50 high-tech companies, foster technology and entrepreneurial growth, and build an innovation economy. The Tech Index helps measure and track the state of the region's economic health. Linda Katehi, UC Davis' sixth Chancellor, and Kevin Surace, CEO of Serious Materials and 2009 Entrepreneur of the Year as recognized by Inc. magazine, were the event's featured speakers.
