• Acquired exper@se in lab techniques: – Cell culture, RT-‐PCR, immunocytochemistry, protein blo^ng and perfusion
fixa@on of hearts, etc.
• Addi@onal exci@ng technologies: – Microarray, proteomics, NMR(Nuclear magne@c resonance spectroscopy), etc
• Observa@on of pharmacological regula@on of heart repair following injury
• Co-‐authored one paper • Next paper in prepara@on
– (A cardiogenic small-‐molecule that regulates myocardial metabolism, heart func@on and survival by Schneider et al)
• Contribu@on of GPR68 adenovirus data to future papers.
