Health and Natural Sciences Consulting Projects
This section contains a non-exhaustive list of Statistics consulting projects I worked on which subject matter relates to the fields of natural and health science. A link to the final project outcome is provided when the client allows for it.
Influence of Weed Height on Oxin Herbicide Efficacy
October 2015 -- May 2017 · Botany and Plant Pathology R | SAS
October 2015 -- May 2017 · Botany and Plant Pathology R | SAS
- Used a factorial design within a randomized control block design to model relationship between treatment and horseweed height.
- Conducted a Dose Response statistical analysis ( ED50 ) to study efficacy of 3 herbicides for controlling horseweed plants.
- Wrote function which estimates the confidence intervals for the difference in dose response (ED50) using boostrap method.
Effect of the Pharmacist-managed Cardiovascular Risk Reduction Services on Diabetic Retinopathy (DR) Outcome Measures
August 2018 -- April 2019 · Pharmacy R | SAS
August 2018 -- April 2019 · Pharmacy R | SAS
- Performed a retrospective case-control study data analysis of patients with diabetes seen/not seen by pharmacists to determine the potential role of pharmacists in DR progression.
- Wrote code to automate data retreival, cleaning and preprocessing from REDcap database.
- Conducted analysis comparing control and treatment group distribution.
- Modelled the odds of rethinopathy worsening in control and treatment groups using a weigthed logistic regression controlling for demographic and health background variables.
- Conducted power analysis to determine sample size for a follow-up prospective case-control study.
Examining the Effect of Structural Priming in Young, Senior and Aphasic Speakers
August 2018 -- December 2018 · Speech Language & Hearing Sciences R
August 2018 -- December 2018 · Speech Language & Hearing Sciences R
- Used a mixed effect logistic regression with maximal random effect to model structural priming effect on three groups of speakers.
- Use contrasts to compare the effect of transitive, dataive and locative structural priming between different speaker groups.
- Conducted sample size estimation for a follow-up repeated measure study design.
Validating New Electromyography (EMG) Sensors for Muscle Performance during Swallowing
November 2018 -- February 2019 · Speech Language and Hearing Sciences SAS
November 2018 -- February 2019 · Speech Language and Hearing Sciences SAS
- Compare the performance of newly developed Electromyography (EMG) sensors with conventional sensors.
- Proposed a Latin square design to validate the use of the EMG sensor in remote monitoring of muscle performance during swallowing.
- Conducted a non-inferioty and an equivalence statistical test on signal-to-noise ratio between the the EMG and conventional sensors.
