“André is a progressive-thinking interdisciplinary scholar and educator working at the intersection of modern assessment systems and innovative scoring, reporting and feedback tools targeting knowledge evaluation. He blends a thoughtful, influential communication style with expert technical skills—a unique combination that allows André to collaborate effectively with researchers and practitioners with equal adeptness.”
– Jeff Harring, Professor, University of Maryland College Park
“I've been collaborating with André for fifteen years and I can tell you why: keen analytic skills, able to synthesize ideas across research areas, excellent communicator in writing and speaking, and high vision of excellence for himself and the team. Our projects have revolved around evidence-centered assessment design, advanced measurement models, cognition and assessment, and new forms of assessment such as interactive simulations.”
– Robert Mislevy, Frederic M. Lord Chair in Measurement & Statistics, ETS
“André devotes his complete attention to every task, which results in high-quality work products. André possesses a high level of technical understanding of psychometrics, statistics, and data science. What sets him apart from others in his field, however, is his ability to communicate complex subjects to audiences of all technical levels. He is an excellent and prolific writer who is widely read and highly cited. Above all else, André is a happy person has great interpersonal skills. Working with him is a joy.”
– Jonathan Templin, Professor and E. F. Lindquist Chair, University of Iowa
“André is a principled research scholar, a passionate member of the measurement community, a caring mentor, and an overall wonderful human being. He was a thoughtful leader who remedied issues with research, helped shepherd his staff's work to the next level, and served as a career advocate.”

“André thinks deeply about all aspects of automated scoring, from engine design and development, to methods around engine training and validation, to operational considerations in scoring, and, finally, to consequences of use. As importantly, André is a delight to work with -- he's funny, warm, thoughtful, and collegial. This combination of deep technical know-how and great personality make him a tremendously valuable colleague. I personally hope to collaborate with André for many years to come!”
— Sue Lottridge, Senior Director of Automated Scoring, Cambium Assessment
“I met André more than a decade ago. In addition to his depth and breadth of measurement and assessment topics, he is also an excellent teacher and collaborator. Most importantly, though, I have consistently found André to be a stellar human--thoughtful, rigorous, kind, funny, and creative!”
— Val Shute, Endowed Professor of Education, Florida State University
“What I appreciate most about André is how he thinks about the big picture regarding research. Not only does he have strong technical skills, but he also thinks critically about why one would pursue a particular line of inquiry, how to best represent the results of research that comes out of that line of inquiry, and how to insure that the presentation of those results has impact.”
— Ed Wolfe, Principal Research Scientist, ETS
“André is a highly competent colleague with amazing skills in psychometrics, methodology and educational assessment. I was fascinated by his commitment, his expertise, and his social competence. His enthusiasm as well as his expertise tremendously increased the motivation of his co-operation partners. It was always a pleasure to work together with Andre.”
— Olaf Köller, Managing Director of Research, IPN Kiel
“André is a steward of our profession, serving individuals and small groups as a teacher and mentor. His broad view of the field, deep understanding of the intersecting needs of research and practice, and his respect for stakeholders with different backgrounds and purposes make him an ideal collaborator.”
– Roy Levy, Associate Professor, Arizona State University
“One can find many psychometricians with the technical wherewithal to analyze or interpret data, but what is unique about André is the broader interdisciplinary lens he brings to thinking through problems and solutions. His intellectual curiosity and enthusiasm for helping others is infectious.”
– Kristen Huff, VP Assessment and Research, Curriculum Associates Inc.
“I have known André for eight years and have worked together on several innovative assessment projects. In each of these projects, Andre brought an immense amount of practical knowledge from all areas of educational measurement and assessment. His wealth of expertise in areas, such as game-based assessment, statistical modeling, and automated scoring to name a few, proved to be invaluable. His ability to channel his theoretical knowledge into practical real-world applications of assessment is of tremendous value.”
— Vandhana Mehta, Research & Evaluation Lead, Cisco Networking Academy
“André’s profound knowledge, caring personality, and eagerness to help junior scholars made my experience of working with and learning from him a sheer pleasure. He is absolutely a great mentor and great colleague for anyone that needs help, guidance, or support in the field of measurement worldwide.”
