Wang Evaluation Consultants



Jacob Curtis, Ph. D.

Everything I know about data science, I learned from Dr. Wang. I worked on his research team from 2014 to 2018. During that time, I learned programming, how to build machine learning models,...

how to create effective visualizations, how to present findings to stakeholders, how to collaborate on a data science team, and much much more.

Dr. Wang is an excellent data scientist. Over our time together, he and the team he led built dozens of machine learning models to solve problems related to education and health. He was passionate about always learning new data science techniques to improve the work. Because of his passion for learning and improving, he has a deep knowledge of data science and ML/AI techniques.

Dr. Wang is a one-of-a-kind leader. He works towards creating an environment where everyone can flourish. He truly cares about those he leads. To this day, he still regularly checks in on me to see how I’m doing. Now that I’m manage my own data science team, I look to him as an example of the type of leader I want to be.

I don’t think it’s an overstatement to say I owe my career to Dr. Wang. I’m very lucky to have had him in my life.

William "Buddy" Gerber, MPA, Ph. D.

I count myself lucky to be one of the many to have been mentored by Dr. Wang. Through his tutelage I have not only found a passion for data science, but aspire to have the understanding and ability to transfer that knowledge in the manner that Dr. Wang can.

Being part of the team that he put together to analyze complex issues developed skills that are beyond what formal education can attain.

Not only is Dr. Wang highly skilled in data science, he has a perspective that can make the complex appear simple. I have been fortunate to work with him on Machine Learning (ML) analysis of substance use and criminal justice. His understanding and application of ML concepts is remarkable. I have not met anyone with as deep of an understanding of the multiple statistical methods and models. His passion for staying on the cutting edge of analysis is evident in not only his abilities, but also in his ease of explaining new technologies.

Being a part of Dr. Wang’s team explains 100% of the variance in my statistical capabilities. I have also been able to glean a perspective to look at issues more critically, and determine the best avenue for analysis. Working with Child Protective Services provided difficulties due to the patchwork of data and issues. However, through analysis, Dr. Wang was able to lead the team to develop relevant understanding and provide solutions for outcomes.

I recommend Dr. Eugene Wang for all statistical analysis, specifically ML. I cannot think of anyone who has more abilities or experience in analyzing social sciences. His understanding of governmental programs, substance misuse, criminal justice and child welfare are beyond compare. His integrity only adds to the mixture of abilities. Any job that Dr. Wang is involved in will be done transparently and honestly. Skill, integrity, and leadership are the best adjectives I can think of in describing Dr. Wang.

Kelly Chroback, M.S.W., LMSW

I have had the privilege of learning from and working for Dr. Wang since 2019. Ever since I met him, I have been impressed with his many academic and professional skills, as well as his willingness to impart his knowledge to the students he mentors.

Dr. Wang has helped me foster and focus my passion for data analytics by helping me focus, teaching me programming skills, how to build machine learning models, and how to translate the results to individuals outside of academic institutions.

Dr. Wang is a superb data scientist and mentor. In the short time I have known him, he has dedicated himself to building various machine learning models to solve problems related to substance use, risk of recidivism, risk of sexual violence, and many other social problems. His understanding and application of machine learning concepts, and his ability to foster these skills in his students and employees is extraordinary. Dr. Wang’s abilities have had, and will continue to have, tremendous payoffs in the realm of various social problems.

Dr. Wang embodies everything I hope to be as a researcher, a professional, an employee, and a mentor. He has supported me, encouraged me, and inspired me in ways I am unable to sufficiently articulate. His mentees and employees love him and appreciate his humorous, helpful, patient, and encouraging manner. I am honored to learn from and work for him and I look forward to many more years of collaboration with him.
