Personal profile

Research Focus

Alejandro Javier Paredes is a Pharmacist with a PhD in drug delivery. During the best part of the last 8 years, he has been working with a focus in pharmaceutical technology, particularly in the oral and transdermal administration of poorly-soluble drugs.

His main research topic has been the formulation of drug nanocrystals using top-down techniques. During doctoral work, he focused on the development of novel nanocrystalline formulations of the antiparasitic drug albendazole. With a strong emphasis in optimizing the manufacturing process, he combined high-pressure homogenisation and spray drying to obtain redispersible powdered formulations for oral administration. Further in vivo characterisation of the systems included the pharmacokinetic and efficacy evaluation in mice and dogs.

His postdoctoral work in Argentina aimed at the development of drug nanocrystals by media milling. There, they designed a novel device to produce nanosuspensions, eventually leading to the development of several new research lines in human and veterinary medicine, as well as in agricultural sciences.

Microencapsulation of drugs and essential oils has also been an important part of Dr Paredes’ work, participating in several collaborations with food scientists. Aiming to different goals, these projects dealt with the microencapsulation of various active compounds using the spray drying technique.

As a postdoctoral researcher, he visited the University of the Basque Country, Spain and the University of Pavia, Italy where he worked in groups of reference in the development of new drug delivery systems for gene therapy and wound healing, respectively.

Dr Paredes currently works as a Research Fellow at Queen’s University Belfast, UK, where he focuses on the formulation and characterization of microarray patches for long-acting intradermal drug delivery. 


Alejandro Paredes has been a teacher of Pharmaceutical Technology from 2012 to 2019 with a tenured position at the National University of Cordoba, Argentina. Besides, he has been an invited speaker at several postgraduate courses. 

As a teacher, Dr. Paredes has been working under the premise that most of the employment opportunities for future graduates in the various fields of pharmaceutical sciences will require a good understanding of the composition, technology and working mechanism behind a certain dosage form.  Ultimately, this holistic training will create Pharmacists with strong technical knowledge but also with a focus on patients' health improvement.


Alejandro Paredes was awarded a competitive Ph.D. scholarship from the Argentinean National Council for Scientific and Technical Research (CONICET) in 2012. During his doctoral studies, he was successful in several applications for traveling funding in national and international calls:

ICTMM 2012 scholarship. To attend the XVIII International Congress for Tropical Medicine and Malaria - XLVIII Congress of the Brazilian Society for Tropical Medicine in Río de Janeiro, Brazil.

- Ibero-American University Association of Postgraduates (AUIP) scholarship for a 2-month research visit to the University of Seville, Spain.

- Escala Docente scholarship from Asociación de Universidades Grupo Montevideo (AUGM) for a 1-month scientific visit to the University of La República, Montevideo, Uruguay. 

- Cooperation South-South (Fo-Ar) bilateral project between Argentina-Cuba 2016-2017, which involved 8 scientific missions between both countries. The Fo-Ar initiative is a competitive call funded by the Ministry of Foreign Affairs, Argentina. The group was also successful in the call 2017-2018.    

After his Ph.D. graduation, he received a Postdoctoral Fellowship from CONICET and funding to make a 6-month research visit to the University of the Basque Country, Spain (2018). 

In 2019 he was awarded a CICOPS Fellowship from the University of Pavia, Italy, where he was a visiting researcher for 4 months.

In September 2019 he started working as a Research Fellow at Queen's University Belfast.

Regarding scientific publications, Dr. Paredes has published several articles in peer-reviewed journals and participated as an inventor in 2 patents. Moreover, he has presented several peer-reviewed abstracts in national and international conferences.
