Building a Research Portfolio

Why You Need a Research Portfolio

Your research portfolio is your professional calling card. It shows potential collaborators, employers, and the research community what you can do - not just what you say you can do.

What a good portfolio does:

  • Showcases your best work
  • Demonstrates your skills
  • Tells your research story
  • Makes you discoverable
  • Opens opportunities

What to Include in Your Portfolio

1. About Section

  • Who you are
  • Your research interests
  • Your background
  • What you’re currently working on

2. Projects (3-5 best projects)

Each project should have:

  • Clear title and description
  • Problem statement
  • Your approach
  • Key results/findings
  • Technologies used
  • Links to code/paper
  • Visualizations

3. Publications & Presentations

  • Papers
  • Conference presentations
  • Posters
  • Blog posts

4. Skills

  • Programming languages
  • Tools and frameworks
  • Domains of expertise
  • Statistical methods

5. Contact Information

  • Email
  • GitHub
  • LinkedIn
  • Twitter/X (if relevant)

Platform 1: GitHub Profile

Your GitHub is likely the first place people will look.

Organizing Your GitHub Repositories

Best practices:

  1. Pin your best projects (you can pin up to 6)

  2. Use clear repository names:

    • hospital-readmission-prediction
    • project1 or final-version-really-final
  3. Write excellent READMEs:

## Overview
Predicts 30-day hospital readmission risk using electronic health records (EHR) and machine learning.

**Key Results:**
- 85% accuracy on validation set
- Identified top 5 risk factors
- Reduced false negatives by 20% vs. baseline

## Quick Start
```bash
# Clone the repository
git clone https://github.com/yourusername/readmission-pred.git
cd readmission-pred

# Install dependencies
pip install -r requirements.txt

# Run the model
python train.py --data data/patients.csv

Dataset

We use the MIMIC-III dataset (publicly available with credentialing).

Methodology

  1. Data preprocessing (handle missing values, outliers)
  2. Feature engineering (create risk scores, interaction terms)
  3. Model training (Random Forest, XGBoost, Neural Network)
  4. Evaluation (accuracy, precision, recall, F1, AUC-ROC)

title: "Climate Change Impact Analysis"
date: 2025-01-15
tags: ["climate", "satellite-data", "python", "machine-learning"]
featured_image: "/images/climate-project-header.png"
---

## Overview
This project analyzes 20 years of satellite imagery to quantify climate change 
impacts on global vegetation patterns.

## Motivation
Climate change is affecting ecosystems worldwide, but comprehensive analysis 
of vegetation changes at scale has been limited. This project fills that gap.

## Data
- **Source:** NASA MODIS satellite data (2000-2020)
- **Coverage:** Global, 250m resolution
- **Size:** 500GB of imagery
- **Variables:** NDVI, EVI, surface temperature, precipitation

## Methods
### 1. Data Collection
Downloaded MODIS tiles using Google Earth Engine API.

### 2. Preprocessing
```python
import ee
import geemap

# Initialize Earth Engine
ee.Initialize()

# Load MODIS data
modis = ee.ImageCollection('MODIS/006/MOD13Q1') \
    .filterDate('2000-01-01', '2020-12-31') \
    .select(['NDVI', 'EVI'])

# Calculate annual means
annual_means = modis.map(lambda img: img.reduceRegions(
    collection=regions,
    reducer=ee.Reducer.mean(),
    scale=250
))

3. Analysis

  • Trend analysis using Sen’s slope estimator
  • Change point detection using BFAST
  • Spatial clustering of similar patterns

4. Visualization

Created interactive maps using Folium and Plotly.

Key Results
