Scraping Social Media Photos Posted in Kenya and Elsewhere to Detect and Analyze Food Types
Published in International Workshop on Multimedia Assisted Dietary Management, 2019
We propose a scrape-by-location methodology to create food image datasets from Instagram posts. We applied our techniques to the millions of Instagram posts we collected across Kenya over a period of 20 days to give an example of the kind of analysis social scientists may conduct with our tools.

A method for detecting text of arbitrary shapes in natural scenes that improves text spotting
Published in Computer Vision and Pattern Recognition Workshop, 2019
UHT, short for UNet, Heatmap, and Textfill, uses a UNet to compute heatmaps for candidate text regions and a textfill algorithm to produce tight polygonal boundaries around each word in the candidate text.

Deep-learning–driven quantification of interstitial fibrosis in digitized kidney biopsies
Published in The American Journal of Pathology, 2021
Our framework to analyzing microscopic- and WSI-level changes in renal biopsies attempts to mimic the pathologist and provides a regional and contextual estimation of IFTA. Such methods can assist clinicopathologic diagnosis.

Semantic-Based Sentence Recognition in Images Using Bimodal Deep Learning
Published in IEEE International Conference on Image Processing, 2021
Semantic-based Sentence Recognition (SSR) can efficiently understand the context between regions of text or between words in images by extracting sentences or paragraphs from images instead of only isolated text regions or words.

A deep learning-based graph-transformer for whole slide image classification
Published in IEEE Transactions on Medical Imaging, 2022
We present a Graph-Transformer (GT) based framework for processing pathology data, called GTP, that interprets morphological and spatial information at the WSI-level to predict disease grade.

Computational Assessment of Early Diabetic Nephropathy
Published in Journal of the American Society of Nephrology, 2022
A deep learning framework known as a feature pyramid network (FPN) was implemented to classify digitized renal biopsies as class I or II DN. Our study identified several regions on the biopsy images as informative for prediction of class I vs II DN. Further analysis can elucidate the importance of various histopathological features of early stage DN.

Graph perceiver network for lung tumor and bronchial premalignant lesion stratification from histopathology
Published in The American Journal of Pathology, 2024
We present a graph-based deep learning framework that leverages hematoxylin and eosin–stained pathology images to stratify bronchial premalignant lesions and predict their progression to invasive lung squamous cell carcinoma.

Graph attention-based fusion of pathology images and gene expression for prediction of cancer survival
Published in IEEE Transactions on Medical Imaging, 2024
We present an attention-based fusion architecture that integrates a graph representation of pathology images with gene expression data and concomitantly learns from the fused information to predict patient-specific survival.
