I have expertise in spatial data analysis and modeling using both open source and propereitry software such as QGIS, ArcGIS, CloudCompare, Photogrammetry software and more.
I have expertise in geodatabase management, photogrammetry, and LiDAR, sUAS, GPS data collection and analysis with proficiency in GIS. I used them extensively during my Ph.D. work, including image processing, analysis, data integration and manipulation. I also have expertise in R, Python, Tableau, SQL, SatScan, CloudCompare, and big data processing
My wide experience in different fields provided me with a unique skill of understanding the complexity of different projects and effectively collaborating with different experts to reach a solution. I am a great listener, that allows me to understand multiple perspectives and make decisions about complex situations/problems. My wide exposure to different work environments taught me adaptability and gel with the existing team to pursue the shared mission and values of the team/organization.
After finishing my PhD this year, I joined the esteemed GIS Team of DFW International Airport where I create custom maps and integrate infrastructure and assets information in GIS and share with stakeholders.
Developed a framework to integrate 3D visualization of utility assets to geodatabase to create a holistic digital representation of the utilities and their assets. This includes the LiDAR dataset, structure from motion (SfM) 3D models, and 2D feature class and associated attributes
Developed customized geospatial solutions that include web maps and dashboards where users can visualize and interact with the infrastructure and assets in real time. Multiple single-click forms were created where users can ask for customer feedback and monitor the response in real-time.
• Conducted indoor field surveys to carry out QA/QC of the spatial data. The data were updated using ArcGIS Survey123 and Quick Capture apps and subsequently updated in geodatabase. Also, it trained users to conduct indoor and outdoor field surveys.
As a Ph.D. student, I did breakthrough research in the microtopography of forested wetlands. This research has opened new avenues for researchers in analyzing ecosystem parameters and hydrological connectivity based on microtopography.
Worked with US Forest Service as a lead researcher on microtopography and its impact on carbon dynamics in tidal freshwater forested wetlands
Led two projects for the North Carolina Department of Transportation (NCDOT); field data feature engineering using total station, RTK GPS, Sonar, and UAS and conducted geographic information science (GIS) and photogrammetric analysis. • Performed technology transition of GIS-enabled spatial analytics and visualizer dashboard to Gastonia County for contaminants in groundwater wells and Mecklenburg County to analyze the accessibility of daycare centers by different communities.
Developed and maintained civil infrastructure and utilities, managed GIS-based substations, and created customized geospatial solutions. • Project Management with multiple stakeholders in engineering application projects. I also led a team that developed first ever GIS standards for the Corps of Engineers.
Participated in United Nations peacekeeping mission in the Democratic Republic of Congo (DRC), where I led a team of engineers who developed civil infrastructure and planned and developed drinking water and electric supply installations for UN forces utilizing limited resources under constrained environment.
I worked on several strategic innovation projects where I acted as a key player and lead researcher from start to end of the projects. Checkout these awesome work and see the images in 'Activity section'
Working with US Forest Service in Santee Experimental Forest South Carolina, as a lead researcher on microtopography and assessing its impact on carbon dynamics in tidal freshwater forested wetlands using biogeochemical modeling.
Performed field data feature engineering using total station, RTK GPS, Sonar, and UAS and conducted geographic information science (GIS) and photogrammetric analysis. I applied data fusion techniques to combine terrestrial LiDAR, sonar, RTK GPS, and sUAS data to develop a seamless microtopographic model of the region under the hydraulic structure.
In this project I created dashboard for Mecklenburg County which displayed daycare accessibility by different communities based on their income and ethnicity.
I prepared maps for Gastonia County which visualize the concentration of contaminents (Arsenic, Lead, Chromium, Nitrates, Nitrites, and Coliform) in groundwater wells of the residents. These maps are used in the Gastonia County groundwater well dashboard.
