Hobbs, Philippa Anne (PhD)
Philippa Hobbs, currently a postdoctoral research fellow with the SARChI Chair:
South African Art and Visual Culture at the University of Johannesburg, graduated
with a National Higher Diploma in Fine Art (with distinction) from the Technikon
Witwatersrand, in 1987 and with an MA Art History (with distinction) from the
University of the Witwatersrand in 2004. In the late 1990s, she started working with
the MTN SA Foundation, becoming Senior Manager in charge of the Arts and
Culture portfolio between 2009 and 2014. An accomplished printmaker and curator,
she is also an art historian who has published numerous journal articles and book
chapters. Co-author (with Elizabeth Rankin) of Printmaking in a Transforming South
Africa (David Philip, 1997), Rorke’s Drift: Empowering Prints, (Double Story Books,
2003) and Listening to Distant Thunder: The Art of Peter Clarke (Standard Bank,
2011; Penguin Random House, 2014), she was also the editor of Messages and
Meaning: The MTN Art Collection (David Krut Publishing, 2006).
In her ground-breaking thesis, Philippa Hobbs examines the tapestry practice
initiated and run by Swedish artists at the Evangelical Lutheran Church Art and
Craft Centre in Rorke’s Drift during the 1960s and early 1970s. Gender politics
provide a lens for her investigation of both the philanthropy of the Swedes and the
responses to it by isiZulu-speaking women who joined the weavery. Through close
analysis of tapestries, many of which were formerly unknown, Hobbs reveals how
women assumed agency by reworking oral narratives in such a way that their works
commented on apartheid policies, missionary strictures as well as limiting social
conventions. Her three examiners – all international scholars – were unanimous in
their praise of the study. Commenting how the thesis brings to light works by
women that were formerly neglected in scholarship, they also observed that
Philippa Hobbs’ thesis provides an outstanding example of how feminist analysis
can enable wholly new perspectives on histories.

Nkomo, Malvin (DPhil)
Malvin Nkomo was born in Bulawayo, Zimbabwe, in 1984. He received a Bachelor
of Engineering Honours degree in Electronic Engineering from the National
University of Science and Technology in Zimbabwe in 2009. In 2012, he completed
a Master’s of Science degree in Communication and Information Engineering at
Shandong University of Science and Technology in Shandong, China. In 2015, he
proceeded to pursue his doctoral studies at the University of Johannesburg. He has
vast industry experience in the field of embedded systems design, having started
his career as a junior engineer at MH Automation and continued to become a
seasoned research, innovations and design engineer at Econet Wireless. He is also
a technology entrepreneur who founded Hailer Technologies − a Pan-African digital
on-demand mobility platform.
In his doctoral research, he focused on advanced wireless sensor networks (WSN)
in heterogeneous internet of things applications, bringing near-cloud computing
competencies to the edge of the WSN. He proposed a novel architecture that
implements virtualisation and overlay networks as on-demand applications at the
edge of the WSN enabling a sensor-as-a-service paradigm to shared sensor
systems, thereby improving energy efficiency, communication latencies and
network congestion.

Abdulrahman, Kamardeen Olajide (PhD)
Kamardeen Olajide Abdulrahman was born in Kaduna, Nigeria, in 1983. He
obtained a Bachelor of Engineering (BEng) degree in Mechanical Engineering from
the Federal University of Technology, Minna, Nigeria, in 2008. He further attended
the University of Derby, England, where he obtained a Master of Science (MSc)
degree in Mechanical and Manufacturing Engineering in 2014. In February 2017,
he registered for a doctoral degree at the University of Johannesburg, South Africa.
He is a registered member of the Council of Regulation of Engineers in Nigeria
(COREN) and currently works as a Lecturer at the University of Ilorin, Nigeria.
The material world faces increasing challenges in dire need of durable materials for
advanced applications. The candidate’s doctoral study focuses on the effect of
deposition parameters and preheating of substrate on the properties of fabricated
titanium aluminide using the laser deposition technique. He carried out an extensive
study on the deposition of titanium aluminide powder (Ti-4822-4 or Ti-Al-Nb-Cr in
prealloyed proportion) on pure titanium (CP-Ti) substrates using three scenarios
(unpreheated, laser preheated and heating-bed preheated substrates). Deposited
samples were characterised through visual observation, microhardness,
microstructure, X-ray diffraction, dry-sliding wear, corrosion and nano-indentation
test for hardness, modulus of elasticity, stiffness and creep. The result outcome
revealed that careful control and increase in energy intensity (most especially
increase in laser power and a reduction in the scanning speed), can totally
eliminate cracks and lead to the production of superior titanium aluminide
composite material suitable for high temperature applications.

Damisa, Uyikumhe (PhD)
Uyikumhe Damsia was born in Lagos, Nigeria, in 1988. He earned his Senior
Secondary School Certificate in 2005, and obtained his Honours degree in
Electrical and Electronics Engineering from the University of Lagos in 2010. In
2015, he obtained a Masters’ degree from the same university, and enrolled for a
doctoral degree at the University of Johannesburg in 2017. While studying for the
degree, he served the University as tutor, demonstrator, student assistant and
lecturer.
The advancement of energy management techniques paves the way for increased
adoption of renewable energy resources, thereby reducing the carbon footprint of
utilities, communities and countries. In this doctoral research, energy management
models for renewable energy-assisted prosumer microgrids were developed. The
models were formulated as constrained optimisation problems whose solutions
minimise the operating cost of microgrids, while satisfying grid constraints. Using
the models, the use of batteries and dispatchable loads in dealing with the
uncertainty introduced by intermittent renewable energy resources, demand and
prosumers, was explored. The models were validated using test systems, while an
algebraic modelling language solver was used for model validation. Results showed
the positive impact of demand-side participation on the operational economics of a
microgrid. Improvement and implementation of the proposed energy management
strategies would facilitate consumer participation in grid power balancing and, the
integration of renewable energy resources.

Gbadamosi, Saheed Lekan (PhD)
Saheed Lekan Gbadamosi was born in Nigeria in 1985. He obtained the BTech
(Honours) degree in Electrical and Electronic Engineering from the Ladoke Akintola
University of Technology, Nigeria, in 2009. He obtained an MEng in Power System
Engineering from the Federal University of Technology, Akure, in 2014. He enrolled
for a PhD in Electrical Engineering at the University of Johannesburg in 2017. He is
a registered Candidate Engineer with the Engineering Council of South Africa
(ESCA) and a registered Professional Engineer with the Council of Regulation for
Engineering in Nigeria (COREN). His research interests include power systems
operation and planning, renewable energy optimisation and power quality.
Electricity generation via conventional generating systems grapples with
challenges, including emission of greenhouse gases, uncertainty associated with
fossil fuel prices and incidences of failure or outages of generators. This thesis
investigated a solution methodology that includes high utilisation of offshore
renewable energy sources and the incorporation of economic incentives to
encourage the use of renewable energy sources. Furthermore, the thesis
developed optimisation models for improving the power quality and reliability of
power systems with large-scale renewable energy sources. A novel method for
estimating Locational Marginal Prices (LMP) as a function of harmonic power
losses was also developed. The developed technique shows an effective approach
to the minimisation of nodal marginal prices, harmonics and power losses coupled
with grid voltage profile enhancement. Lastly, a reliability framework for the
integration of large-scale renewable energy sources into a power system was
considered with the end result being increased grid dependability and reliability.

Mahajan, Sagar Bhaskar (PhD)
Sagar Bhaskar Mahajan was born in India on 25 June 1989. He received the
Bachelor of Engineering degree from the University of Mumbai, India (2011), and a
Master’s in Power Electronics and Drives from the VIT University, India (2014).
Prior to his PhD studies, he was assistant professor at the Marathwada Institute of
Technology, India. His research work related to power electronics, drives and
renewable energy. He is a member of IEEE, including various IEEE societies like
IES and IAS. He is a review member of various journals and conferences including
IEEE and IET. He received the IEEE ACCESS Journal award, Reviewer of the
Month, in January 2019.
Sagar Bhaskar Mahajan started his PhD work related to modelling and circuit
formation of power converters. His work mainly focused on non-isolated
unidirectional power converters and application to renewable energy systems. He
identified design challenges for high voltage converters and derived a novel
configuration based on the multistage concept. He is the first researcher to develop
a new family of power converters called X-Y converter series. The X-Y power
converter family has three classifications: two-stage, three-stage, and N-stage X-Y
power converters. He tested all originally developed circuits in numerical simulation

Mahlobo, Mandlenkosi George Robert (PhD)
Mandlenkosi Mahlobo completed his Chemical Engineering undergraduate studies
at Tshwane University of Technology before enrolling for his MTech studies in
2012. His MTech research was completed cum laude in 2016 producing two
international conference publications. He enrolled for his PhD at the University of
Johannesburg in 2016 and was awarded the NRF Travel Grant to the University of
La Rochelle (France) where he spent 15 months working on his research. His
research has so far produced three conference papers, a Best Presentation Award
at the University of West of Scotland, and he recently submitted three articles for
journal publication.
The rationale behind the research was to establish a reliable method for estimating
and monitoring the corrosion phenomena occurring in buried pipeline steels and to
understand their cathodic protection efficiencies in varying soil environments. The
specifically modified voltammetry technique in combination with electrochemical
impedance spectroscopy and linear polarization resistance used in this study
provided insights into the degradation processes occurring at the steel/electrolyte
interfaces in soil environments. The study approach demonstrated that cathodic
protection effects and the varied wet-dry cycles largely influenced the oxygen mass
transfer mechanism, interfacial pH and electro-capillarity effects that led to the
formation of a pseudo-passive mineral layer covering steel surfaces and the
calcareous deposits that inhibited corrosion. The study revealed that cathodic
protection efficiency was primarily linked to the polarisation level, the properties of
the calcareous deposit, and those of the pseudo-passive oxide layer.

Global population and economic growth has increased waste generation and the
introduction of emerging contaminants into water streams that may pose sanitary
and environmental risks. These contaminants have increased the demand for new
approaches that address emerging pollutant removal in wastewater streams.
Wastewater treatment is inherently a dynamic process because of the large
variation in the influent concentration, flowrates and composition, which makes it
difficult to control the time-varying process parameters. The candidate applied
mass balance equations, the activated sludge model and artificial neural network,
using MATLAB, to predict and forecast the flow rates, the emerging micropollutants
concentration and their composition, biosolids utilisation and sludge
biochar utilisation in wastewater treatment plants. This combined knowledge of the
process dynamics with the prowess of mathematical models for evaluation of
wastewater treatment processes addressed the challenges posed by controlling the
time-varying process parameters.

Mwema, Fredrick Madaraka (PhD)
Fredrick Madaraka Mwema was born in the South Eastern region of Kenya. He
received his BSc (First Class Honours) and MSc degrees in Mechanical
Engineering from Jomo Kenyatta University of Agriculture and Technology, Nairobi,
Kenya, in 2011 and 2015, respectively. He then registered for a PhD degree at the
University of Johannesburg in January 2017. Mr Mwema is a registered graduate
mechanical engineer with the Engineers Board of Kenya (EBK) and he is currently
an assistant lecturer at Dedan Kimathi University of Technology, Kenya.
Aluminium thin films are used as metallisation networks in micro-electronic devices
and back contacts in solar cells. This is due to the low cost, high contact
conductivity, low diffusion in silicon and sheet resistance of aluminium. These
applications, however, are limited by microstructural defects. The candidate’s
doctoral study focused on the deposition and characterisation of aluminium films
through radio-frequency magnetron sputtering with the aim of achieving defect-free
films. The films were deposited on various substrates under different sputtering
parameters and characterised for structural, chemical and mechanical properties.
Optimised parameters for depositing films of aluminium via RF magnetron
sputtering were obtained in this study. The study revealed that sputtering aluminium
thin films within low temperature range (slightly below 100 o C) produces structures
with no defects. The study demonstrated, for the first time, that defect-free
sputtered aluminium films exhibit fractal behaviour and that fractal prediction can
improve the sputtering of aluminium thin films.

Sithole, Nastassia Thandiwe (PhD)
Nastassia Thandiwe Sithole was born in April 1991. She is currently a lecturer in
the Department of Chemical Engineering at the University of Johannesburg (UJ).
She completed both her Bachelor’s and Master’s degrees in Chemical Engineering
at UJ and has been a full-time PhD student since July 2016. She has published four
journal articles (two articles in press) and seven conference proceedings.
The candidate’s thesis was on waste valorisation, focusing on the beneficiation of
Basic Oxygen Furnace Slag (BOFS), with the purpose of utilising the material in
remediation of acid mine drainage and for construction applications. To achieve this
application value for BOFS, physico-chemical processing was conducted geared
towards improving the properties of BOFS for the aforementioned applications. The
candidate’s work is novel in that minimal work that has been done on utilisation of
BOFS to produce geopolymers for use as construction blocks that meet the
minimum requirements as per ASTM and South African standards. Furthermore,
the application of these developed geopolymers composites as geo-filters to treat
mine water by neutralisation and removal of metals and sulphates is a novel
concept that contributes to the body of knowledge. The treated mine water in this
study met the minimum statutory limits as stipulated in the South African water
quality guidelines.
