• "I highly recommend Dr. Brown as a consultant for biomedical researchers. He has considerable expertise in the areas of study design and statistical analysis, expecially in the area of practice based research, and is very responsive to the priorities and goals of the investigator." Dr. David Katz, Assistant Professor of Medicine, University of Iowa Medical School.
• "Dr. Brown has enormous expertise and skill in the appropriateness and use of the most current analytical methods, and a wealth of experience in working in the areas of health and mental health services research." Professor Mary Ann Test, School of Social Work, University of Wisconsin-Madison.
• "During the past several years Roger Brown, Ph.D. has provided statistical support for two clinical research projects that I have headed. Dr. Brown provided these services on a volunteer basis. The first project was a survey study looking at the demographics of primary care sports medicine physicians in the United States. Dr. Brown was instrumental in helping me develop survey questions that could provide meaningful and clear clinical answers. Once the data was collected, I was impressed with his diligence and expertise in completing the statistical analyses. On several occasions I needed more statistical information on short notice which was never a problem. I also found Dr. Brown to be readily available for questions. The second research project involved a more complex clinical study requiring a number of statistical analyses for which Dr. Brown was again invaluable, both in terms of selecting the best statistical approaches to interpret the data as well as accuracy in completing the analyses. After the study was submitted for publication, he willingly responded to the comments that the reviewers of the journal requested. In summary, I found Dr. Brown extremely knowledgeable, responsive, accessible, and friendly to work with. I would look forward to collaborating with him on future research projects, and would also highly recommend him to others." Dr. Douglas F. Hoffman, Director of Sports Medicine, Physicians Plus Medical Group, Madison, Wisconsin.
• "Dr. Brown is an unusual blend of the highly academic and the eminently practical. He is on the cutting edge of statistical theory and practice, yet able to provide extremely useful guidance on the mundane details that can make or break projects." Dr. Richard Brown, Associate Professor, Department of Family Medicine, University of Wisconsin Medical School.
• "Dr. Brown will contribute a solid knowledge of research methods and up to date statistical techniques to any group that wants to develop a grant proposal, plan a research study, or initiate a program of research development." Dr. Mary Beth Plane, Senior Scientist and Coordinator of Research, Department of Family Medicine, University of Wisconsin-Madison.
• "I have worked closely with Dr. Brown in grant writing, research, statistical analysis and teaching for over 6 years. He is considered a national expert in statistics and has been a large part of my research team's success." Dr. Partick McBride, Dean of Students, University of Wisconsin-Madison, Medical School and Director of Preventive Cardiology, University of Wisconsin-Madison Medical School.
• "As a co-investigator on two research grants, beginning approximately 5 years ago, Dr. Brown has contributed to the development of the research design and planned and given oversight to the analysis of the data. Dr. Brown is exceptionally sensitive to the contingencies of clinical research in designing a research plan, and is highly innovative in the data analytic strategies that he creates. He uses state-of-the-art data analytic strategies, and is continually seeking new strategies to solve data analytic problems. He is a superb consultant in all respects--quickly grasping the research problem, carefully explaining details of a complex analysis strategy, and efficiently executing the data analysis in a timely manner." Professor Karen Pridham, University of Wisconsin-Madison, School of Nursing.
• "Dr. Brown is a highly respected and nationally know for being at the forefront in the development and application of cutting edge statistical techniques. I owe my success in securing funding of two NIMH proposals to the excellent consultation and assistance Dr. Brown provided in helping formulate the study design and statistical analyses." Associate Professor Jan Greenberg, School of Social Work, University of Wisconsin.
• "Dr Roger Brown provides a comprehensive service for any medical researcher needing statistical analysis. He assisits the researcher from the initial planning stage to the final outcome,and explains stastistical concepts in simple terms that can be understood by less-statistically-minded mortals! Alhough this study was done in South Africa,all statistical analysis was done by Dr Brown via e-mail correspondence.He is willing to discuss any queries in a prompt and friendly manner,making the writing up of the results he obtained easier to integrate into the final report. I can highly recommend him." Dr Louise Matthews,M.D.,Principal Medical Officer and PhD student,Department of Obstetrics and Gynaecology,University of Cape Town,South Africa.
• "Dr. Brown's assistance in developing power analyses and statistical models for several major research grant applications has been invaluable. His work has been highly praised in peer reviews of our proposals, and has been instrumental in our obtaining funding. During the actual conduct of the projects, he is able to convey complex statistical concepts in an understandable manner and assist project staff in making difficult design, analysis and interpretation decisions. I highly recommend his services." Dr. D. Paul Moberg, Director and Senior Scientist, University of Wisconsin Center for Health Policy and Program Evaluation.
• "Roger Brown has many professional and personal characteristics that make him an excellent statistical consultant. His professional characteristics include the following: (1) Listens carefully to understand background for study and statistical issues; (2) Gives detailed instructions, advice, and information regarding statistical analyses to beconducted. Provides citations for analyses when needed; (3) Considers practical issues of analyses, letting me know when it would be better if I did time-consuming data management as opposed to him doing it; (4) Very good at explaining the meaning of statistical results and how to interpret them; (5) Knowledgeable about state-of-the art statistical analyses, which in my case involved multi-level analyses, MlWin, and machine learning; (6) Knowledgeable about medical and psychological issues involved in studies, so that he does not focus just on statistical issues, but considers any methodological issues involved; (7) Innovative when appropriate, suggesting novel ways to examine data; (8) Committed to finishing the job, helping me with initial analyses and responses to any reviewer questions. His personal characteristics include the following: (1) Excellent communication skills both in person and via e-mail; (2) Patient and secure in his knowledge, so that he welcomes questions about statistical issues rather than becoming defensive; (3) Supportive of the research involved, doesn't act like an uninvolved bystander; (4) Personable, easy and enjoyable to work with; (5) Dependable, detail oriented."
