Expertise
|
Biochemistry - This includes protein isolation and protein fraction enrichment, Western blot electrophoresis and immunoprecipitation. |
|
Electrophysiology - This includes all aspects of patch clamp electrophysiology and extracellular recording. |
|
Fluorescent imaging - This includes live imaging and calcium-imaging. |
|
Future scientific Plans - Future scientific plans for at least the next 5-8 years will be to work on these three aforementioned projects in which overall goals are to substantially contribute to improving treatment of chronic pain with no opioids. I aim for not only understanding the mechanisms controlling the development of chronic pain, but to also discover promising therapeutic targets. I planned to obtain external funding support for these projects, and develop novel and contemporary approaches to facilitate solving questions raised by these projects. In this regard, our collaborative team is working hard to set up two contemporary approaches: single-cell sequencing and in vivo live imaging with two-photon microscopy. Thus, we (I am PI) submitted an S10 equipment grant to the NIH in June 2018 to support purchasing a 2-photon microscope system. Importantly, I conduct my research program with my graduate students and post-doctoral fellows. Thus, my research and teaching efforts are combined and execute simultaneously to meaningfully address the critical problem of chronic pain. |
|
Molecular and cellular biology - This includes Isolation and synthesis of nucleic acids: DNA and RNA, construction of vectors and libraries, screening of genomic and cDNA libraries, in situ hybridization (non-radioactive and radioactive), and transfection and propagations of cell lines (primary and secondary). |
|
Next Generation Sequencing - This includes RNA-seq from tissue samples and single-cell sequencing. |
|
Pain modulation in pathological conditions - (inflammatory and neuropathic pain) |
|
Research Program - My main area of research interest is to understand how chronic pain develops, especially mechanisms controlling the transition to and resolution from chronic pain conditions. Chronic pain mismanagement has led to opioid overuse, overdose related deaths and cardiovascular, renal and neurological complications at epidemic proportions. In this regard, several Institutes and Centers across the NIH support the ?Acute to Chronic Pain Signatures program?, including UM1, U24 and U54 funding opportunities. To address mechanisms of chronic pain, I started (from 2016-2018) three independent projects related to sex-dependent mechanisms of pain chronicity, age-dependent mechanisms of pain chronicity and peripheral mechanisms of pain chronicity. Projects associated with sex-dependent mechanisms of pain chronicity were recently (2018) awarded with two R01 grants (R01 NS102161 and R01 NS104200). Of particular relevance, these two new R01 grants were scored at the 1% and 2% levels (i.e., they better scores than 99% and 98% of all grants submitted to the NIH, respectively). This provides an independent assessment of the scientific impact of my research program. The other two project lines will form the basis of two additional R01 grants to be submitted in FY19. |
