My Projects

Predictive modeling

Used machine learning technique (extreme machine leaning) to predict phytoplankton (algae) population in Lake George, FL. Also used optimization technique to enhance the performance of machine learning

Exploratory data analysis

Used Python library such as pandas, matplotlib and seaborn to explore and pre-process diabetes data set. Applied extra tree classifier to help with feature selection in modelling process.

Visualizing Geospatial data

Applied data visualization library in Python (Folium) to visualize crime rate in San Francisco. This is a part of Data visualization course in Coursera.

Education/certification

What I’ve Learned

June 2019-September 2019 (expected)

IBM Data science professional certificate

This program covered a wide array of data science topics including open source tools and libraries, methodologies, Python, databases, SQL, data visualization, data analysis, and machine learning. In this program I also familiarize myself with IBM products like Watson and Cloud Services.

August 2015-August 2019

PhD Mathematics, University of Florida

My interest lies in Biomathematics which  involve solving real-world problems related to Biology/Ecology. My thesis is to understand the competition dynamic of phytoplankton in freshwater lake by using mathematical modeling which result in publishing a paper in a well-known journal.

August 2013 - May 2015

MS in Mathematics, University of Florida

This program helped me to strengthen my mathematics background such as Probability theory, Numerical Analysis and Differential equation. I also taught in different types of undergraduate classes which helped me gain communication skill, listening skill and time management skill.

My Experience

August 2013 - August 2019

Doctoral Researcher

  • Conducted researches in mathematical modeling for population of phytoplankton focusing on two species competing for the limiting resource in lake's ecosystem.

  • ​Developed predictive model of phytoplankton population by using neural networks

  • Optimized model parameter to enhance the ability of neural networks

August 2014- August 2019

Teaching Assistant , University of Florida

  • Led discussion sections for undergrad students in various classes such as College Algebra, Survey of  Calculus, Precalculus and trigonometry, Calculus 1,2 and 3.

  • Graded quizzes, homework assignments and exams.

  • Used data from online homework provider to design class activities.

August 2017- December 2017

Researcher, The Center For Stress Resilient Agriculture,  University of Florida

  • Collaborated with graduate students from agricultural and biological engineering department and a private biotech company, to investigate the best mechanisms to deactivate marine diatom. 

  • Studied the effect on growth rate of diatom under unfavorable environment.

  • Designed a sample plan to monitor the effectiveness of the deactivation

August 2018 - May 2019

Organizer for Biomath Seminar at Department of Mathematic

Scheduled time and location for the seminar. Coordinated with faculty to invite speakers across department for the seminar. Sent out email announcement and a thank you email to the speaker after the talk. Maintain and update website
