Data Scientist / Statistician with a passion for data analysis

I believe that words and data are the two most powerful tools to change the "world". I am mostly programming and working on gaining insights from large data sets and interpreting them. My skills include network & statistical data analysis, data visualization, machine learning, and statistical consulting. I have developed a keen understanding of problem-solving and enjoy challenges.

Recent Publications

As a research associate, I have published several papers with various co-authors from different disciplines. You can check some of these papers here.

Iterative Estimation of Mixed Exponential Random Graph Models with Nodal Random Effects

Iterative Estimation of Mixed Exponential Random Graph Models with Nodal Random Effects

We introduce a new estimation framework in ERGMs iterating between pseudolikelihood and maximum likelihood estimation approaches for nodal effects and network statistics.

Publication
Bipartite Exponential Random Graph Models with Nodal Random Effects

Bipartite Exponential Random Graph Models with Nodal Random Effects

We examine the inclusion of specific nodal random effects for first- and second-mode nodes for bipartite networks. The predicted nodal random effects deliver reasonable interpretation to understand the network behavior.
