Dr Huaiyu Yang is Lecturer in Biocrystalliation in the Department of Chemical Engineering. His research is always multi-disciplinary, including; biopharmaceuticals crystallisation; downstream manufacturing; crystallisation of small organic molecules; interface phenomena; nanotechnologies; and; stable and unstable phase diagrams. Before he joined Loughborough as a lecturer, he spent his years in Tianjin University, KTH Royal Institute of Technology, Strathclyde University and Imperial College London for undergraduate study, PhD and postdoc research.

My research ranges from small organic molecules to large biomolecules, from fundamental nucleation theory, to pharmaceutical industrial projects, and from molecular interations, to scaling up and continuous crystallisation.

Area 1: Biocrystallisation in Downstream Separation Process

Fast developments in the upstream production of biopharmaceuticals, drive the downstream separations (DSB) of biopharmaceuticals as a bottleneck for the whole bioprogress. Crystallisation of proteins, including biopharmaceuticals, is a potentially feasible biotechnology in downstream bioseparation for purification and isolation. My research try to develop new generation of platform for biocrystallisation, and the intergration between biocrystallisation and other biotechnologies to overcome the barriers in the DSP. 

Area 2: Nucleation and Crystallisation on interfaces between solid, liquid (liquid-liquid) and gas phases

My research try to demonstrated how the interface can be engineered to control crystallisation of biopharmaceuticals and polymorphs of small molecular pharmaceuticals. The designed and engineered surfaces, between between solid, liquid (liquid-liquid) and gas phases, been applied to control the (bio)crystallisation process.

Area 3: Cell in vivo crystallisation

My research try to find out suitable environments to generate in vivo crystals and environments of growing bigger protein or biomedicine crystals, and by apply different biotechnologies to smartly connecting these stages. 

Area 4: Nanodrop crystallisation

My interest is to generate nano-crystal by nano-drop or nano-devices, to stabilize of nano-size organic or protein crystals by nano-technologies or biotechnologies, to find the applications of nanoparticles with nano-biomedicine in smart drug delivery.
