Senior Research Officer
PhD
Ahmed has developed strong machine learning expertise throughout his undergraduate, Masters and PhD degrees. He has expertise in supervised and unsupervised statistical modelling, linear regression, maximum likelihood estimators, bootstrap sampling and Bayesian statistics to mention few. He mostly uses Python and R to perform statistical calculations, with seven years of experience in Python and one-year experience with R. During his PhD degree and postdocs, he has been managing extremely large dataset (terabyte scales) and performing extensive analysis and visualization of this dataset.
Ahmed is currently interested in applying his computational experience in medical imaging & research and has recently joined the MAP team as a senior research scientist. His role involves mapping the burdens of Plasmodium falciparum and Plasmodium vivax malaria through spatiotemporal and statistical modelling infrastructure to predict malaria transmission and burden sub-nationally, nationally and globally and across a wide range of epidemiological settings.

WALLABY Pilot Survey: H i gas kinematics of galaxy pairs in cluster environment
We examine the H i gas kinematics of galaxy pairs in two clusters and a group using Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pilot survey observations. We compare the H i properties of galaxy pair candidates in the Hydra I and Norma clusters, and the NGC 4636 group, with those of non-paired control galaxies selected in the same fields.

We study the tidal interaction of galaxies in the Eridanus supergroup, using H i data from the pre-pilot survey of the Widefield ASKAP L-band Legacy All-sky Blind surveY.
Published research Geospatial Health and DevelopmentFebruary 2022Spatial codistribution of HIV, tuberculosis and malaria in Ethiopia
HIV, tuberculosis (TB) and malaria are the three most important infectious diseases in Ethiopia, and sub-Saharan Africa. Understanding the spatial codistribution of these diseases is critical for designing geographically targeted and integrated disease control programmes. This study investigated the spatial overlap and drivers of HIV, TB and malaria prevalence in Ethiopia.

Although previous evidence suggests that the infection fatality rate from COVID-19 varies by age and sex, and that transmission intensity varies geographically within countries, no study has yet explored the age-sex-space distribution of excess mortality associated with the COVID pandemic.
Published research Infectious Diseases Geospatial Health and Development COVID-19November 2022WALLABY Pilot Survey: Public release of HI kinematic models for more than 100 galaxies from phase 1 of ASKAP pilot observations
We present the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) Pilot Phase I Hi kinematic models. This first data release consists of Hi observations of three fields in the direction of the Hydra and Norma clusters, and the NGC 4636 galaxy group.
Published research Geospatial Health and DevelopmentNovember 2022WALLABY pilot survey: Public release of H i data for almost 600 galaxies from phase 1 of ASKAP pilot observations
We present WALLABY pilot data release 1, the first public release of H i pilot survey data from the Wide-field ASKAP L-band Legacy All-sky Blind Survey (WALLABY) on the Australian Square Kilometre Array Pathfinder.

We present new results of a 12CO(J = 1-0) imaging survey using the Atacama Compact Array (ACA) for 31 H i detected galaxies in the IC 1459 and NGC 4636 groups. This is the first CO imaging survey for loose galaxy groups.
Published researchAugust 2022Spatiotemporal mapping of malaria incidence in Sudan using routine surveillance data
Malaria is a serious threat to global health, with over 95 % of the cases reported in 2020 by the World Health Organization in African countries, including Sudan. Sudan is a low-income country with a limited healthcare system and a substantial burden of malaria.
October 2021WALLABY Pre-Pilot Survey: The effects of angular momentum and environment on the H i gas and star formation properties of galaxies in the Eridanus supergroup
We use high-resolution ASKAP observations of galaxies in the Eridanus supergroup to study their H i, angular momentum, and star formation properties, as part of the WALLABY pre-pilot survey efforts.
Published research Geospatial Health and DevelopmentAugust 2021WALLABY pre-pilot survey: Two dark clouds in the vicinity of NGC 1395
We present the Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pre-pilot observations of two 'dark' H i sources (with H i masses of a few times 108 {M}_\odot and no known stellar counterpart) that reside within 363 kpc of NGC 1395, the most massive early-type galaxy in the Eridanus group of galaxies.
Geospatial Health and DevelopmentAugust 2021WALLABY pre-pilot survey: H i content of the Eridanus supergroup
We present observations of the Eridanus supergroup obtained with the Australian Square Kilometre Array Pathfinder (ASKAP) as part of the pre-pilot survey for the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY).
Published research Geospatial Health and DevelopmentJuly 2021WALLABY Pilot Survey: The Diversity of Ram Pressure Stripping of the Galactic HI Gas in the Hydra Cluster
This study uses H i image data from the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) pilot survey with the Australian Square Kilometre Array Pathfinder (ASKAP) telescope, covering the Hydra cluster out to 2.5r 200. We present the projected phase-space distribution of H i-detected galaxies in Hydra, and identify that nearly two-thirds of the galaxies within 1.25r200 may be in the early stages of ram pressure stripping.
