### Scroll down to see my graphic design work.

Recently I've focused more on my photography work, which is available at my photography __Instagram__.

# UI Design

The example is the UI of Equator Music, a Youtube music player. I created the UI design using Sketch along the various states (showing playlists or songs) and icons for the project.

# Logo Design

The example is the Equator Music logo. I generally design logos in Sketch, but have also designed various logos in Illustrator. Check out my other logos by checking out my other projects!

# Misty Mountains

This was a school project that I created in Photoshop with a heavy use of blend modes. The criteria was to create an image that could go along with a haiku.

# Playing Cards

This was a quick school project made in Illustrator with the concept of modern yet authentic "Gills Sans" playing cards in mind.

# Typographic Puma

This was a school project made in Illustrator using words/letters to create an image of a puma.

# Dandelion

This was a picture I retouched in Photoshop mainly using colour curves.

I've focused more on school assignments in the last year. Most are available under "university".

I gave a workshop talk as part of the UofT ISSC (Independent Summer Statistics Community), where I both created my own materials for both a lecture style talk and applied hands on portion. The lecture section covered motivations for Bayesian Stats, motivations for priors, weakly informative priors, and Bayesian predictions. The hands on portion covered a multiple imputation random effects model using Stan and Python interfacts.

Check out the finalized slides and workshop notebook.

# UofT ISSC Bayesian Workshop

# ISSC Case Competition 2021

My group of 4 (Ashley Zhang, Sergio Zheng Zhou, and Muhammed Tsany) created a slide deck and write up that won the best insight award out of 16 competing teams that were ultimately accepted. The event was hosted as part of UofT's Statistical Sciences Summer Community. We created our a custom dataset from open source data and explored how education and income levels could be related to liveability scores (inspired by the Economist's). Ultimately, we found potential evidence of a "mobility ceiling" between the second highest income bracket and the highest, and suggested possible future investigation directions.

My group of 4 (Ashley Zhang, Sergio Zheng Zhou, and Muhammed Tsany) created a slide deck and write up that won the best visualization award out of 17 competing teams (out of 70+ teams that applied). Judges came from Amazon, BMO, Dalla Lana School of Public Health, KPMG, TD Insurance and more. We explored how income levels could be related to misuse across drug categories, and how certain drug survey questions would be linked with drug misuse across categories. Ultimately, we found income brackets at the extremes were linked to higher drug misuse and certain more personal survey questions had statistically significant effects across drug categories.

# ASA DataFest@UofT 2021

# ASA DataFest@UofT 2020

My group of 4 created a Tableau dashboard that portrayed the Canadian consumer landscape through a basket of common consumer goods, inspired by CPI. Our analysis centered on careful descriptive analytics on manually cleaned data, filtered by exploratory data analysis. We found the prices of our basket of goods had been negatively affected by the pandemic.

# Open Source Pause Menu

A robust open source pause menu for Unity3d that controls and saves relevant video and audio settings. It currently has over 6000 users and a 5 star rating on the asset store.

Check out the project page here.

# uDocumentGenerator

A modern, light, and organized documentation generator. It was born out of the drawbacks I had while using Doxygen to create documentation for Open Source Pause Menu.

# Academics

### Relevant courses sorted by year and category

Only some coursework is shared since others may contain code, derivations, etc..., that would be unwise to make public.

# First year

## Statistics

## STA130

**An Introduction to Statistical Reasoning and Data Science: ** This course taught
the foundations of data science and statistical reasoning through "a combination of
logical thinking, mathematics, computer simulation, and oral and written discussion
and analysis". It ultimately covered traditional statistical methods along with
foundations of supervised learning and some models.
In every tutorial, we analysed a problem using statistical methods
and presented our conclusions to the class. A more detailed description is available
on the calendar (course
catalogue) or at the course website.
The course culminated in a group data analysis project that analysed global internet
usage with R on a multitude of factors, e.g,
region and socioeconomic status.

Check out the final project slideshow.

## Theoretical Computer Science

## CSC165

**Mathematical Expression and Reasoning for Computer Science: ** This course was
an introduction to theoretical computer science with an emphasis on developing the
foundations of "abstraction and rigour". The course used proofs to develop "precise
expressions of mathematical ideas, including definitions and theorem" and mainly
applied them to the running times of iterative programs (Big-Oh, Big-Omega,
Big-Theta). A more detailed description is available
on the calendar (course
catalogue) or at the cached course website.

Check out problem set 4: our work or the handout.

## Programming Based

## CSC148

**Introduction to Computer Science:** This course taught the much of the
foundations of computer science using python. The main concepts covered were
"Abstract data types and data structures for implementing them. Linked data
structures. Encapsulation and information-hiding. Object-oriented programming.
Specifications. Analyzing the efficiency of programs. Recursion." Our final project
(assignment 2) was to create a recursive tree-based data structure that would
represent music efficiently (and thus be able to play correctly formatted songs).
The course website is no longer up, but here is the syllabus.
More information about the course is also available on the calendar.

## Mathematics

## MAT137

**Calculus! (Calculus with proofs): ** This course covered differential and
integral calculus with an emphasis on proofs. Ultimately this course expected us to
know how to the theoretical foundations of calculus concepts in conjunction with the
computational methods. For example, it was expected of us to be able to use the
formal definition of a certain series to prove its divergence. More information is
available on the calendar
(course catalogue) or find some of the course materials used in one section.

# Second year

## Statistics

## STA247

**Probability with Computer Applications: ** This course taught the foundations of
probability through calculations and some proofs of core concepts. Notable concepts
include: "random variables, discrete and continuous probability distributions,
expectation and variance, independence, conditional probability". These concepts
were applied to
various common distributions not limited to the normal, exponential,
poisson, and geometric distributions. More information is
available on the calendar
(course catalogue)

## STA248

**Statistics for Computer Scientists:** This course covered inferential and
descriptive statistics from an applied and computational perspective. Assignments
heavily used R to perform data analysis using concepts such as hypothesis testing,
confidence intervals, regression and ANOVA. Proofs were sometimes used to reinforce
theoretical foundations. More information is
available on the calendar
(course catalogue)

Check out some questions that I did in R:

## Theoretical Computer Science

## CSC236

**Introduction to the Theory of Computation:** This course was a rigourous
introduction to the Theory of Computation. It covered topic such as various forms of
induction, running times of recursive algorithms, program correctness, and state
machines (NFAs and DFAs) using formal languages. The course consisted of weekly
quizzes, tests, and assignments that would consist of proof based questions. A more
detailed description is available
on the calendar (course
catalogue) or at the course website.

## Programming Based

## CSC207

**Software Design: ** This course was a project based course, covering software
design concepts, namely SOLID design principles and design patterns noted by the
Gang of Four. Practical experience of design patterns and SOLID design principles
were reinforced by practical experience in using Android Studio to create a game in
a group setting. Emphasis was placed on writing clean code for future extensibility.
A more
detailed description is available
on the calendar (course
catalogue).

## CSC209

**Software Tools and Systems Programming: ** This course covered programming in
bash and C. Emphasis was placed on being able to utilize bash commands to
efficiently assist in develop programs in C in addition to writing Bash programs.
Assignments required C and Bash, and the final assignment focused on creating a
twitter-like sever and client, with emphasis placed on correctly writing
asynchronous and synchronous code. A more
detailed description is available
on the calendar (course
catalogue).

## Mathematics

## MAT235

**Calculus II: **This course taught multivariate calculus, covering vector
calculus,
line integrals, and surface integrals in addition to differential and integral
calculus of multiple variables. Additionally, emphasis was placed on applications
from mainly physics and sometimes statistics. A more
detailed description is available
on the calendar (course
catalogue).

## MAT223

**Linear Algebra I: **This course covered core concepts in linear algebra, such as
eigenvalues and eigenvectors, spans, linear dependence/independence, cross/dot
products, and linear transformations. A more
detailed description is available
on the calendar (course
catalogue).

## Economics

## ECO101

**Principles of Microeconomics: ** This course taught the foundations of
microeconomics. It covered core concepts such as pricing, externalities, taxes,
introductory game theory, and monopolies. Emphasis was placed on developing
intuition of market movements and the resulting prices. A more
detailed description is available
on the calendar (course
catalogue).

## ECO102

**Principles of Macroeconomics: ** This course taught the foundations of
macroeconomics. It covered core concepts such as GDP, CPI, international trade,
tariffs/taxes, monetary supply, and PPP. Similar to ECO101, emphasis was placed on
developing intuition of market movements, but we used macroeconomic models in
determining the behaviour of markets and resulting prices.
A more detailed description is available on the calendar (course
catalogue).
