Semel Institute Biostatistics Core (SIStat) is a team of expert biostatisticians,
methodologists and research support staff. The mission of the
Core is to foster
research productivity and quality by helping faculty design sound
research projects, obtain independent funding, and analyze data
correctly. Grant development services such as design and statistical consultation, power analysis, and analyses of pilot data are available to Semel Institute and all UCLA faculty without charge.
Continuing Core services to funded projects and programs are negotiated on a case by case basis. The Core provides investigators from fully-affiliated projects and their statistical staff access to SIStat consultation, data analysis and programming services, up to one year post-funding support for final, "clean-up" data analyses, and permanent archiving of data. SIStat also offers fee-based consulting and data analysis to Semel Institute and all UCLA faculty. From time to time, faculty of the Core also provides education in statistics and research methods to interested faculty, staff and students.
SIStat services are available to:
|Junior faculty who do not have research funding.
|Any faculty member preparing an application for extramural
|Extramurally funded faculty who want ongoing, fee-based
statistical support for their project(s).
|Students at all levels enrolled in educational programs
in the Semel Institute.
|Catherine Sugar, Ph.D.
Catherine Sugar, Ph.D. is an associate Professor in the Department of Biostatistics
and the Director of the Semel Institute Statistics Core (SIStat) in the
Department of Psychiatry and Biobehavioral Sciences at the University of California, Los Angeles. She received
her Ph.D. in statistics from Stanford University in 1998. Dr. Sugar's methodological
expertise is in clustering, classification, and functional data analysis with
an emphasis on finding patterns in high-dimensional or longitudinal data. She
has also been involved in numerous applied projects in the mental health arena,
particularly in schizophrenia and depression. This work has focused on identifying
patterns of symptoms or functioning in patient populations and exploring how
those patterns evolve over time in response to treatments or other stimuli.
Dr. Jim Mintz, Professor in UCLA’s Department of Psychiatry, has
been a clinical research methodologist for over 35 years. He received
a PhD in Clinical Psychology in 1969 at NYU under the mentorship of Jacob
(“Jack”) Cohen. During the next decade at University of Pennsylvania’s
Department of Psychiatry he established an international reputation as
a psychotherapy and substance abuse researcher. Dr. Mintz moved to UCLA
in 1979, and for almost two decades headed the Methodology and Statistical
Support Unit in the UCLA Center for the Study of Psychosis...

|Damla Senturk, Ph.D
Damla Senturk, Ph.D. is an Assistant Professor in the Department of Biostatistics at the University of California, Los Angeles. She received her Ph.D. in statistics from University of California Davis in 2004. Dr. Senturk's main methodological research areas are regression model building for repeated measures/ longitudinal data, functional data analysis and semiparametric covariate and error adjustments in regression and correlation models with applications to biomedical data. She works on modeling trends in data that are changing over time and explore dynamical regression relations between variables. Some of her applied work include modeling of molecular inflammation markers, infection status and cardiovascular events in the dialysis population, risk factors for hypertension, genomic markers of disease outcome and association of molecular measures in female carriers of the FMR1 (fragile X mental retardation 1) gene.
