Research Interest

1. Medical Physics 
Focus estimation of dose to the breast as a result of exposure to machines producing ionization radiation-mammogram (publication sent to journal). Using MCNP6, we simulate the energy deposited from proton and heavy ions beams to estimate the energy lost outside the region of interest. In addition, we experimentally investigating the effect of such beams on the normal tissue and cells adjacent to the cancer region during the cancer therapy in collaboration with biology and nutrition scientists at Texas Tech and other Universities. Comparing the dose from MCNPX and the effects (obtained experimentally) we will be able to find the relationship between the dose and the damage/effect beyond the assumed tumor region (SOBP) with various medically significant parameters (tumor depth and location in the human body). 

2. Exposure to human from infinite surface source
Using Geant4, we would like to know the exposure vs. height to human from infinite surface source on the ground due to the deposition of radioactive materials as a result of accidental release (from nuclear power plant or other accident) (publication in preparation).

3. Gel Dosimetry
Many complex medical physics work requires radiation dose delivery which requires dosimeters capable of accurately measuring complex, three-dimensional dose distribution with good spatial resolution. MAGIC-f polymer gel is one of the emerging new dosimeters which is widely used in research in medical physics. We are on the study to present a overview of polymer gel dosimetry using MAGIC-f gel, including its composition, manufacture, imaging, calibration and application to medical physics research. We are doing both computation and experiemntal studies of irridation of vial consisting of MAGIC-f gel. (publication in preparation).

4. C. elegans as model organism 
Aging is a complex process that involve a stochastic event which occur at the molecular level in mamals. C elegnas been excellent models of metabolic diseases and aging research, given their short lifespan compared to humans. We are testing the impact of various radiation exposures across lifespan. We expose C. elegans to gamma irradiation at different ages and determine both theoretical modeling for radiation exposure using Monte Carlo Methods (Geant4) to model the position of the samples under the beam and to estimate the absorbed dose required before running the irradiation experiments, as well as to determine experimentally, the biological impact of radiation on aging and its reversal or reduction by tart cherry anthocyanins.We are addressing the effect of gamma exposure on human at different ages during the time of relevant applications such as evacuation after the occurrence of nuclear accident using the existing data of the external exposure from Chernobyl and Fukushima accidents or using C. elegans as model organism.(publication in preparation

5. Theoritical Calculation of Non Polar Surface Area Using Implicit Solvent Method
Microheterogeneity still presents a challenge for correct glycan isomer identification, even with combinations of techniques, such as LC-MS. In this context, nonpolar surface area (NPSA) has been shown to correlate quite well with LC retention times (RT) in a C18 column for glycans. Hence, accurate theoretical estimations of NPSA through fast and reliable quantum chemical protocol could provide an invaluable tool in biological samples analysis. So, we are proposing this protocal.(publication in preparation).

6. Renewable Energy
a. Gravitational Water Vortex micro hydro system modelling, design, testing and feasbility (few conference papers and journal article in process)
b. Feasibility study of distributed wind energy system, solar PV system, wind-solar integration and other renewable energy system in various part of the world.(publication in preparation)  

7. Miscellaneous
I am open to collaborate in the various research related to engineering and science.
