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.

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).

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)
