Problems in Clinical Trials
In 1997, I completed my undergraduate degree in statistics
of the Universidad Veracruzana, México and
followed it, in 1998, with a postgraduate qualification in Statistical Methods
from the same institution. While I was doing my initial post graduate study, I also
worked part-time as a lecturer (at Universidad Veracruzana) teaching courses
called Laboratory of Exploratory Statistics, Statistical Methods and
Statistical Consulting to students on the undergraduate degree in statistics.
On Completing my initial post graduate qualification, I
obtained a job as a Departmental Supervisor for the Teacher Modernization
Department at the General Coordination of Mexican Ministry of Public Education
(SEP) States Committee. In this role I had responsibility for day to day administration
activities and statistical analysis of survey data. Having obtained practical
experience over 3 years (1998-2001), I then applied for a scholarship to study
for a PhD and, in autumn 2001, I moved to Sheffield with funding from CONACYT
to study statistics with Dr. Nick Fieller
I am interested towards the methods
based on covariate-adaptive randomization in clinical trials. When the number
of patients is small with a relatively large number of prognostic factors
(i.e., covariates), and if the patient information is available in advance then
it may be possible to use a sequential randomization technique, which takes
into account (or adapts) to the values of the covariates of the subjects
already randomized to treatment groups. It should be different form adaptive
randomization schemes which take into account the treatment outcomes of
subjects previously randomized to treatment.
Because my working experience, another
of my interests is Statistical Consulting. Some of the projects where I worked
were focused on nutritional and dietary diagnoses; political opinion surveys;
supply and demand studies for two university courses (public accounting and
computer science) at Universidad Veracruzana, México.
