I
am currently in my fourth year of graduate study here at Ohio State
University. I am pursuing a Ph.D. in Economic and Engineering Analysis
of Biocomplex Systems. This one-of-a-kind degree program has emerged
from graduate studies in economics and statistics in conjunction
with my research with Dr. Bakshi's PSE Group. To learn more about the
motivation and content of my studies, be sure to read my statement
below.
What's New
My
current work revolves around the study of statistical properties of
life cycle inventory (LCI) models which often combine economic
input-output data with more specific engineering process data. I
am particularly interested in characterizing the discrepancies that
arise when different inventory models (e.g. process-sum LCI, EIOLCI,
tiered-hybrid LCI) are applied to the same network. These
discrepancies are due in part to the degree of aggregation present in
the input-output data, selection of process LCI boundary, and producer
price variability. With assumptions about these sources
of variability, I am exploring the distributional properties of
the vector of residuals (life cycle emissions and natural resource
consumption) associated with each inventory method. This may
yield some insight into the importance of boundary selection and
enhance inventory results in terms of accuracy and reproducibilty.
I am applying this framework to a case study for coal-fired
electricity generation.
In the near future I hope to extend these results to data at the many spatial and temporal scales encountered throughout a material's life cycle with the goal of establishing a link between social and economic policies and the outputs of these engineering models.

Additional Readings
(updated periodically) -- This is just a short list of readings about
the interdisciplinary approaches in engineering and the social sciences
and in complex systems modeling. My interests have been tied
closely to materials production and use, but a number of other needs
and applications for such interdisciplinary approaches have been
identified in the references below.
