If your goal is to memorize formulas, pass an exam, and move on, I am not the right fit.
I work with people who want to understand how things actually work end-to-end—and how to use that understanding to make better decisions in real situations.

If your goal is to memorize formulas, pass an exam, and move on, I am not the right fit.
I work with people who want to understand how things actually work end-to-end—and how to use that understanding to make better decisions in real situations.

I am driven by one goal: creating meaningful impact at the individual level. Whether I am teaching, building systems, or advising, I focus on helping people make decisions they can trust, gain clarity, and develop capabilities that translate directly into their work and lives. My technical background—a Ph.D. in Industrial Engineering with a focus on statistics, optimization, and computational methods—serves this goal, not the other way around. I have applied these foundations to real-world problems through data science, machine learning, and production AI systems, allowing me to connect abstract concepts to tangible outcomes.

I have been teaching since 2009 across institutions including the University of Redlands, California Polytechnic State University, and Mississippi State University. My experience spans large lectures (200+ students), small group settings, and one-on-one instruction. I have taught Data Science Foundations, Data Mining, Predictive Analytics, Data Visualization, Prescriptive Analytics, Linear Programming, Statistics, Probability, and Engineering Economy across undergraduate, graduate, and professional levels, in in-person, online, and hybrid formats.

My approach is structured but individualized. I focus on how each person thinks, where they get stuck, and what outcome they actually care about. From there, I build intuition first—why something works—then translate that into execution using Python and modern data tools. I avoid rote memorization and instead emphasize problem-solving, decision-making, and confidence through hands-on work.

The objective is not just to learn a concept, but to be able to use it—correctly—when it matters.

Approved Subjects

Data Analysis

Data Analysis

I hold a PhD in Industrial Engineering with a strong focus on data analysis, statistics, and optimization. I have taught multiple data-focused courses, including Data Science Foundations and Data Mining, at institutions such as University of Redlands and California Polytechnic State University. In industry, I have built end-to-end data pipelines and machine learning systems, working with large-scale datasets and real-time decision systems. My approach emphasizes practical analysis using Python, helping students move from raw data to clear insights and actionable outcomes.
Data Science

Data Science

I hold a PhD in Industrial Engineering with a focus on data science, machine learning, and optimization. I have over a decade of teaching experience, including courses such as Data Science Foundations and Predictive Analytics at University of Redlands and California Polytechnic State University. In industry, I have designed and deployed end-to-end data science systems, including large-scale data pipelines and machine learning models used for real-time decision-making. I focus on helping students understand core concepts and apply them using Python to solve practical, real-world problems.
